Airtel — outgoing sms stopped

Address:

Chennai, Tamil Nadu, 600097

My name is srinivas and i am airtel customer since more than 10 yrs (Too bad). I had a problem sending sms (Outgoing only) and not a single network engineer at airtel customer care is able to solve it since 4 months. I think airtel doesn't care about their customers anymore except takes their money month over month promptly. Stop showing ads about no 1 data/network provider and start addressing customer care issues. Hope some one bothers to respond

Regards,
Srinivas p
