Below is my letter to the Nodal officer of Airtel Karnataka. I'm posting on my blog in the hope other people avoid signing up for this service.

Hello,

As a long time airtel customer, and a current customer of both DSL (about 1.5k per month) and Mobile (about 3k per month) I am DISGUSTED by the level of customer service I have received trying to pay for yet another airtel service (4G Dongle).

I request that you immediately activate my account, and I request you take action against Regional Communications (particularly Anand who I have been dealing with) and inform me of the result. His number is 9686868683. I would recommend his contract be cancelled. In addition, I request a credit on my account for the immense amount of time I have wasted in this matter (literally 20+ phone calls).

Background:
I purchased a 4G dongle from Purohit computers in BDA Complex HSR Layout Bangalore on Tuesday the 25th of February. I was told it would take 2 days to activate. It has been 12 days and the agent in charge (Anand from Regional Communications) is now hanging up on me and blocking my calls.

I have submitted all documentation required.
