Paytm — Cash back of Rs.3000 not paid

Address:

New Delhi, Delhi

I have bought a samsung galaxy a7 from reliance digital xpess, G.K. 1 New Delhi. At that time there was an offer from paytm of getting a rs.3000 cash back i.e. rs.500 for 6 months to ur paytm wallet. Intially there was sone problem with the server of paytm, so i could get an access to that offer/code after 2 months and also after 2 months when the dealer provided me code for the cash back that code was not working. When i made several complaints to the dealer he told me to contact the paytm care. Even the paytm care is not giving any answers to it. Please help me into it. Email- [protected]@gmail.com
