Paytm Mobile Solutions — not resolving my problem regarding voucher code

On 2nd feb 2018, i was doing dish tv recharge suddenly i started looking for some cash back offers.
I got one with ucb (United colors of benetton) there is mentioned if i purchase something from united colors of benetton store then paytm will give me 300 cash back. I said ok and taped on offer.
After purchase what i found 2k extra deducted from my account. I tried to call paytm regarding the same but guess what they even not respond to any of the number they provided online.
Ok, i thought than why don’t i use that voucher if i already paid for that.
I went to a united colors of benetton store to buy some stuffs.
I had words with the store manager regarding the same that i have a united colors of benetton voucher and he said i can’t use that voucher offline i have to use it online.

I tried that too but voucher is invalid.

So i sent a mail to paytm regarding the same that i am not able to use that ucb voucher.
I got reply that
