Home grown popular e-commerce site, Flipkart has reportedly begun sending apology mails to beleaguered consumers over the Monday's (6 October) Big Billion Day flash sale fiasco.

Despite minting huge revenue (close to $100 million/more than ₹600 crores) out of Big Billion Day gala, Flipkart's much hyped flash sale faced severe criticisms over the poor handling of servers, which were unable to cope high incoming traffic volume leading to outages and sudden cancellation of the purchase.

Some people were in the middle of the purchase process and could not get confirmation on their order due to the site crash. Whereas, others found most of the items with 'out of stock' signs and for some devices, the price-cuts were revoked within a few minutes after 8:00 am sale kick-off time.

In the letter to consumers, Flipkart co-founders - Sachin Bansal and Binny Bansal have apologized for not living up to the expectations of the loyal patrons as promised.

The company has accepted the criticisms constructively to improve the service for future exclusive sales day, by scaling up the infrastructure and other back-end jobs to handle more user-traffic volume.

Monday's - Big Billion Day was Flipkart's largest discount sale since in its inception; this poor show will be taken as a lesson for future sales and an opportunity to learn from big firms like Amazon, eBay and those in developed markets – Best Buy, Carphone Warehouse that attract millions of consumers on Black Friday and Cyber Monday.

Here is the full script of Flipkart's apology mail:

"Dear Customer,

Yesterday was a big day for us. And we really wanted it to be a great day for you. But at the end of the day, we know that your experience was less than pleasant. We did not live up to the promises we made and for that we are really and truly sorry.

It took enormous effort from everyone at Flipkart, many months of preparation and pushing our capabilities and systems to the limit to be able to create this day. We were looking at fulfilling the dreams of millions of Indian consumers through deals and offers we had painstakingly put together for months.

And though we saw unprecedented interest in our products and traffic like never before, we also realized that we were not adequately prepared for the sheer scale of the event. We didn't source enough products and deals in advance to cater to your requirements. To add to this, the load on our server led to intermittent outages, further impacting your shopping experience on our site.

An unprecedented 1.5 million people shopped at Flipkart yesterday. While we stand humbled by the sheer faith that such a large number of customers have shown in us, we are unhappy that we were unable to live up to the expectations of millions more who wanted to buy from us yesterday.

And this is not acceptable to us.

Delighting you, and every single one of our customers, is absolutely the top most priority for Flipkart and we have worked very hard over the last seven years to earn your trust. Yesterday, we failed that trust. We have learnt some valuable lessons from this and have started working doubly hard to address all the issues that cropped up during this sale.

Price Changes As we were preparing various deals and promotional pricing in the lead up to the sale, the pricing of several products got ​changed to their non-discounted rates for a few hours​. We realise that this breaks the trust our customers have put in us. We are truly sorry for this and will ensure that this never happens again.

Out-of-stock Issues We ran out of the stock for many products within a few minutes (and in some cases, seconds) of the sale going live. For example, most of our special deals were sold out as soon as they went live. We had ensured availability, anywhere from hundreds to a few lakh units for various products, but it was nowhere near the actual demand. We promise to plan much better for future promotions and ensure that we minimise the out-of-stock issues.

Cancellations We had large number of people buying specific products simultaneously. This led to some instances of an order getting over-booked for a product that was sold out just a few seconds ago. We are working round-the-clock to ensure availability of additional units for these products and will do our level best to ensure that we minimise any cancellations.

Website Issues ​We realise that the shopping experience for many of you was frustrating due to errors and unavailability of the website at times. We had deployed nearly 5000 servers and had prepared for 20 times the traffic growth - but the volume of traffic at different times of the day was much higher than this. We are continuing to significantly scale up all our back end systems so that we do a much, much better job next time.

Everything that we have achieved at Flipkart is purely on the basis of our customer's trust and faith. This is why we come to work each day and continue to remain extremely passionate about building the best possible customer experience for Indian consumers. We failed to live up to this promise yesterday and would like to apologise once again to every single customer for our failure.

Thank you.
Sachin and Binny"
