Me from TamilNadu using AirTel.
Previously I was an AirTel prepaid customer and later changed myself to postpaid due to a availablity of an affordable scheme.
At the time of prepaid to postpaid conversion I was troubled a lot- They simply disconnected my prepaid account and the postpaid account was activated only after 38 hours!!
My business was heavily affected on that 36 hrs- as I was left with a blank mobile!
I just list out some of the problem I faced:
Customer care- They are not aware of what AirTel offers. Each one gives different info, finally u are confused and u go mad ! Some time u can see some wrong info’s posted in https://airtelworld.com & when enquired to customer care, they simply ignore it.
Their e-mail to mobile messaging is NOT reliable. It never reaches the receipiant. In my experiance the probability is 1/50
For every SMS you sent u receive 2 delivery report. Immediatly after u send the SMS, u can see the ’Pending’ message & within 2-10 sec another message comes depending on weather its delivered or not and again some bluffing response given by Cust care for this problem.
Be ware - Never download any ringtone, picture messages from Yahoo, bcos it wont get delivered ( I hav experianced) but u will be charged for that !! And, when I contacted the customer care they agree that there is some problem. But any how they will cost you (!!)
You will face some signal drop ie., You will be having full signal & u are near to a tower, and in the middle of a conversation the call will be disconnected & u ar surprised to see the signal strength reached zero level & after some time it rises up.I have faced this more than 2 times also with different handsets.
National & Internatinal SMS are costly compared with BPL and Aircel.
Low coverage compared with other 2 players.
Fraud Billing: They may charge u for what they have told u as free. Once, some 50 SMS were said as free for me, but I was shocked to see the itemized bill where they have charged for the same. And, finally with long argument with cust care they cleared the charges.
