Paytm — regarding placing order and getting rejected for no cause

Address:

500083

I have placed the order on 31st march, 2019. I have purchased this on application of coupon code of cashback of 1250/-. And after few days it got delayed due to some aspects. I have spoke to the customer care of the paytm. They have said me to wait for few days. And i have waited as they said but today they have cancelled it. And i spoke to them they are saying sorry to me.
Please, my hearty request to all indians, non-indians to not to purchase from it.
