Paytm — False recharge done in my account

Address:

Mumbai City, Maharashtra

I have done recharge of 52 rs and it was showing full talktime on site but it something done false recharge by Airtel and now PayTm and Airtel both have denied for this mistake. I am really frustrated with this type of fraud. When I buy something online then they guarantee that it has safe business but now this is just worst case. Please help if anybody can or just don't trust this type of fraud sites.
