Airtel — activated topdoctorsonline

Airtel activated topdoctoronline on my mobile. What is topdoctoronline? I never activated any offer. They deducted 49 rs from my balance. They cannot activated offers like this. I complained to airtel but no response. This never happened before but airtel should fix this. Check your records airtel and give us our amount back. Never do that again. You are losing our trust.
