It's not recommended to deal with newbies when it comes to any Indian wallet cash and since BTC is irreversible, users need to be cautioned.
you are new user on this forum and trying to buy bitcoin with paytm mode
better to try Localbitcoins or this website - trybitcoin.in . They both charge minimum fees
Even LBC users cannot be trusted as I was already scammed by a LBC user. Trybitcoin can be better.
