Airtel — dth error code 6

Address:

Kolkata, West Bengal, 700030

I have recharged my airtel account no [protected] by inr 650. When i saw that the same error code is displayed even after 20 mins, i called up customer care who confirmed of resolving it yesterday by 5pm. However no one called up and today got an sms that they were unable to connect me. I logged the complaint again and the irresponsible cust care person said that tomorrow a call will be arranged at 3 pm when i'll be at office. I explained that i can't bee at home @3 pm and arrange the call after 6 pm but he refused.

I am surely frustrated and thinking of writing in social network so that others don't fall into the same trap.
Worst experience ever.
