Amazon India — Amazon fake promotion & without customer person taking there own decision due to that I am loosing

Hi Friends,

Please do not buy from Amazon below many ways they are fooling customer with fake promotion.

1. Amazon members will have early access but better offers for non-prime members. I purchased as phone with exchange phone on 2nd October 2021 that day for realme 3 pro exchange value is 5000rs but after prime early acces next day exchange values is 11300rs on 4th October 2021 there is difference of 6300rs.
Below ways they blocking the offer and not allowing the customer to cancel order and not to replace new order.
1. They are blocking the entered IMEI number and showing error as already purchased in exchange with this IMEI number, you can't use this IMEI number.
2. Card discount is lost again they can't use the card for discount.
3. EMI will not be cancelled as refund will be split and given as phone amount, 100 rs pickup charges and if you taken any protection plan that one, but when you applying EMI while buying will take all together.
I spoked to the customer care without giving any resolution they disconnecting calls.

Flipkart is way far better in the sales, they offer given to flipkart members will be best deal than flipkart non plus members.

After purchasing in Amazon If I canel also loss or keep the order also loss.
