Hi Mutaji,
I recommend you to check our website Trybitcoin.in to check out the reviews of the users, who have and are using our service currently.
The main idea of our service is to provide bitcoin's easily and instantly. Many newbies and enthusiasts who we meet everyday want to know more about bitcoin and eventually try them. But most of them get discouraged due to long process they would have to go through to even transact a small value of bitcoin. We want to simplify the process, that is why we introduced complimenting platforms like Paytm and Mobikwik, to allow everybody to Trybitcoin easily.
Is there any proof of your user transaction,sorry to say but there are plenty of scammer here so and i havent heard of any exchange service doing paytm to bitcoin.
You should show us the legit transaction proof in order to allow people to trust and use your service.
