Mts — Threatening advocate calls against the Bill payment

Address:

Chennai, Tamil Nadu

Dear Sir, My name is Anwardeen. I bought MTS Post paid connection([protected]) at 05/May/2014 in Chennai, Tamilnadu but after 5 months I have changed POSTPAID connection to PREPAID connection. When I change POSTPAID connection to PREPAID that time I paid the amount 840 for that month usage. Because without pay the due amount MTS dealer(Big street, Opp to Karur vysya bank atm, Tripilicane, Chennai) told me, they can't the change to PREPAID connection. Then I paid the amount and then it's converted to Prepaid now. Last five months I am getting the call for the payment of 01-Nov-14 to 18-Nov-14 usage. Then I replied to them, already I paid the amount and now am using that as Prepaid connection. Finally now-a-days I am getting calls from Advocates and they are saying due to unpaid amount MTS is going to file the case on you in Delhi high court. I don't know why they are doing like this. Whether the person is Fake or not. I am getting the Advocate call from +91 [protected] this number. Please help me to resolve this. Do I need to pay again? Why they are threatening the customers? My question is without payment how they did the POSTPAID connection to PREPAID connection? Please help me and guide me to solve this issue.
