Airtel - negligence of customer care service

Hi,

I've been Airtel customer for +*years, when I shifted from Noida to Hyderabad. I visited Airtel store and requested to localize & convert one of my mobile numbers from Post paid to Prepaid. I've paid Rs.*** also for the same. After, *months or later I receive a call from customer care that my postpaid bill is pending. I explained that I converted it to pre-paid and as reference I sent photographs as requested. But still I keep receiving recovery calls from different people from customer care, they don't look at the history and past conversation and everyday I get the call but they don't try to resolve it.

I wrote a mail very much in detail of my experience and the problem I'm facing to airtel customer care ***@airtel.com, also copied to nodalofficer.andhra@airtel.com and Ceo gopal.vittal@airtel.com., but there is no reply.

After about a week I get reply saying that they tried to reach me but they couldn't as my mobile (**XXXXX***) invalid. But my mobile is working and I'm receiving calls from Airtel customer care asking to pay dues everyday. I replied asking them to respond by email, but again I get the standard message saying that they tried but couldn't as my mobile number is invalid.

I am very frustrated, it caused lot of inconvenience and mental agony. It is the number (**XX**XX**) used by my wife, it is the primary contact number for her for personal and professional communication. Now, it is blocked since few days.

My experience and problem information is very much detailed in the email attached.

Thanks
Lokesh
