Airtel — prepaid balance to postpaid

Airtel owes me 800+ which was a balance in an addon prepaid

I converted prepaid my main number from prepaid to postpaid at the airtel office in jan 2019 on cbi road, bangalore, karnataka for the 649 family package. I received the first bill in feb. Then in march, i upgraded the package to 799 at the airtel office on

1/97, ground floor, 6th cross, r. T. Nagar main road, bangalore, rt nagar, bangalore, karnataka 560032

I upgraded to be able to addon two existing prepaid numbers in my name to the main number. There was a balance of 800+ in one of the prepaid sim. Before i upgraded i had repeatedly asked the person who attended to me pragna if the balance would be transferred to the main account and she assured me that it would.in fact she said that the march bill would be the balance after deducting the balance

When i received the march bill, to my surprise and shock, the balance was not reflected. So i personally went back to the airtel office at rt nagar, and the manager/supervisor navin attended to me. He told me that he has sent out an email. I specifically asked him if i have to make a payment first and he said it was not required. He said this would get sorted out in a couple of days. This was around april 9/10/11. To my irritation after a couple of days, my number was blocked. So i personally went back to the airtel office at rt nagar. The manager/supervisor again attended to me. He got my number unblocked and he again reassured me that the matter would be sorted out in a couple of days. He even gave me his mobile number incase of problems.

I even sent him a sms on april 17th letting him know that matter has not been solved.

When i didn't get a response, i even tried calling him but he did not pick up the phone.

Last week i received a call from the collection department and i repeated the above incidents. She put me on to her supervisor and he again assured me that this would get sorted out in 48 hours. He also assured me that the late payment fee would be waived. Again nothing was done.

I got another call from the collection department and she asked me to go to an airtel office. So i went to the cbi road branch, bangalore, karnataka.
They asked me to send an email to the nodal officer as they could not do anything and they assured me that this matter would be resolved in 48 hours.

48 hours have passed and long gone...

All i'm hearing is that the matter will be resolved in 48 hours. Quite a few 48 hours have come and gone.

It's a pity that this is happening. I've had the main znumber for over 10 years as a prepaid with absolutely no issue.

Worse still i've been charged a late payment fee in the subsequent fee through no fault of mine. If the 880 which was due to me had been deposited to my airtel account, i would have a balance being carried forward to the next month.

Shouldn't i get a compensation instead of a late payment as there excess???
