Tata Docomo — stay away from this one

Address:

Chennai, Tamil Nadu

Few years back i have used tata docomo but last year itself i have closed my account.Few months back i have received a bill with outstanding amount and when i check the bill it is in another name but my contact number and email id. I was shocked so i have register complaint against this and i asked them to check and close the things, daily im getting more than 5 calls and sms it was irritating me i have raised complaint many times but no action but they have put my name in the credit history so it is affecting me lot due to this i got many problems like if i apply credit cards, loan then they are checking credit history and rejecting my application.. I dont know what to do? they asked me to pay the outstanding amount and then close. How could i do this? it is not in my name and im not using then how could i pay ?
