Reliance Communications — Service is pathatic

I am not able to connect to the internet since Nov 28th. I approached nearest reliance Web world and asked to resolve the problem.
They said, I had very less balance in my prepaid account and asked me to recharge my account.
I have recharged my account, but still I was not able to connect. He told me that some network upgrade is going on in my area and it might take 2 - 3 days to sort out the problem.

I waited for one week, still not able to connect.
Took my device and machine to the Reliance web world. They tried to resolve the problem and they were not able to resolve it.
They have opened a ticket for the same. (Please see below mails for additional info)

I got a call from the technical department after 3 or 4 days saying that I need to take my device to the service centre to get it checked.

I have submitted the device at the authorized service centre one week ago, it was proved that my device was a faulty one and got it replaced from the service centre yesterday.
Still I am not able to connect to the basic internet even though I was said that the new device would be activated in less than 24 hrs.

Now my problem is
I have taken this device for business purposes, and after investing so much on the device and despite of high usage cost, reliance is not able to provide basic connectivity.

Also
In the previous month I have recharged my account, of which not even a single byte has been used by me.
I have discussed the same with the CSR’s and they were not able to carry my balance forward.
I have submitted a complaint in the nearest Reliance web world to resolve this problem.
I want Reliance to do this for me because it’s not at all my fault. I was forced to recharge and my problems were not answered.
I have taken this device for business purposes, and this device and Reliance service has made my life more miserable.
