Airtel Magic - All Cost No Service

Airtel is the largest private mobile services provider in India currently, under the brand of Bharti. They have been reaping the benefits of the growing mobile consumer base and making healthy strides one market at a time. The company has some awesome ad campaigns and probably some of the largest coverage areas in the subcontinent. And now to the cribb.

I have been a customer of Airtel since I came back here in 2004, thats nearly 2.5 years. I was a postpaid customer in Bangalore and now here in Delhi. For starters it was pretty good in Bangalore since I was a customer under Sun Microsystems and well we managed to get some good deals. But when I wanted to get additional services activated or deactivated it was a nightmare. Now around 6 months ago I moved out here to Gurgaon and well decided to stick with Airtel.
0) They did not allow me to transfer my number from Bangalore to Delhi.
1) I got a postpaid connection and first thing they do is set my usage limit to be 700Rs. So if I crossed 700Rs in the first month my service would be automatically deactivated and I wouldnt be able to send/receive calls
2) They don't check for previous records at all. I was an Airtel customer in Bangalore and when I took a connection out here they shouldve atleast given me credit for being a good customer for the past 2 years. I was never late in payments and well thats all that they care about.
3) No Roaming. They are demanding 1500Rs as a deposit to activate my roaming. While this is done hassle free on prepaid cards it seems to be such a big hassle on postpaid. I just cant understand why.

All in all Airtel like any big business house in India seems to treat customers like shit once they have captured the market. The only hope is that TRAI comes up with better policies to help us out with these unnecessary headaches.
