Sir,
I bought hero motocorp vehicle from paytm on oct. 19
Order id. [protected]
In this i was given ₹1000 cashback and ₹4000 promo code in form of 10 voucher of ₹400 each. I used only 3 vouchers and now paytm has flagged my account stating promo code abuse.
Also i bought mobile phone from paytm on 20 dec. But it was automatically cancelled by seller in 5 mins. But have haven't received my money back yet.

Since, i was using promo code given by company, you don't have any right to flag my account on this basis. Unflag my account.
