Airtel — no incoming message

Address:

Chennai, Tamil Nadu, 600130

This is pandiarajan. I am not getting any messages including otp for bank transaction in my mobile network (Airtel). I recharged for a year and lost my money due to otp issue and can't change other network immediately. I complained customer care. They didn't understand the serious ness and they are giving serveral days time look when i call every day. Very very bad experience with airtel network.
