Address: www.flipkart.com

Hi friends,

I purchased a mobile in this flipkart Big Billion sale 2020 after that are giving huge publicity and promotion as below.
1. MarQ by Flipkart Smart Home Speaker (with Google Assistant) @999rs
2. Google home mini @1499rs.
3. Lenovo Smart Clock (with Google Assistant)
4. Mi Smart Speaker (with Google Assistant)

Above mentioned they are promotion they are giving in the form coupons under 'My Coupons' page.

Now I place below three items in the following order ID "OD[protected]"
1. MarQ by Flipkart Smart Home Speaker (with Google Assistant) @999rs
2. Lenovo Smart Clock (with Google Assistant)
3. Mi Smart Speaker (with Google Assistant)

But here comes the big plan by flipkart saying that the items were cancelled by seller

Hello V Srinivas,
You made an excellent choice by deciding to purchase one of the top selling products on Flipkart. However, due to high demand for this item and in order to provide all customers an equal opportunity, the seller had to cancel the following items in your order with OD[protected].

Below are my questions to flipkart.
1. In this order only coupon applied products only cancelled why not remaining items not cancelled.
2. If seller was cancelled the moment I placed the order and before going to payment page received cancelled message.
3. Then why you should allow to select 3 quantity for the product, you can restrict like option more quantity.
4. Then why you are showing as coupon used under my cupon page.
5. Last one, when the same quantity of products purchased by the customer without promotion when you did not cancelled with same reason for the order ID 'OD[protected]'.

The above sale is on 20th October 2020

This kind of issue noticed after every sale. Below is one example on 17th September 2020 & order ID is 'OD[protected]'

So this is complete fake promotion, please do not waste your time and money
