Address:

Hyderabad, 500032

Dear zomato you have done unauthorised transaction without my permission from my paytm wallet.
Transaction id ; ztd-20-8b0a09140d313
Ztd-20-d[protected]a26
And they are not replying my mail from 24-48 hours.
They only told we will shortly contact you.
I have also talked to the paytm they told they need a confirmation from zomato that the transaction was wrong to refund the money.
