Airtel — telecom services

Address:

Chennai, Tamil Nadu, 600017

I am holding a post paid account with airtel and in spite of making surplus amount and that too within due date, my account got deactivated y'day.. I have been calling their customer care for past 2 weeks and also written e. Mails to their official e. Mail ids. They claim that this was due to technical issues at their end but no resolution provided so far. I am completely upset with their poor responsiveness.
