MTS / Sistema Shyam TeleServices [SSTL] — Demanding payment for closed connection

Address:

600037

I was using MTS Dongle under No.[protected] till end of March 16. Since I got retired I wish to discontinue the same and visited their Shop at Ambit mall, Ambattur industrial estate, Chennai on 5th and gave letter to discontinue the same and ready to pay the amount. Since I am closing they calculated the amount till 5th April and collected Rs.1190/- and gave receipt. They taken the letter from me to close the account. After two months I got message from mts through my mobile stating that I have not paid for last 2 months and I have to pay immediately otherwise legal action will be taken. I have sent mail to them stating that I have already given letter for closing hence there is no question of non payment of any due. They replied they have not received any letter and referred the matter to their legal dept., who in turn said they will be force to lodge complaint in Delhi court for non payment. I want to avoid their harassment paid Rs.1543 on 28th June 16 and sent mail immediately that I have paid the amount and wish to close immediately and not responsible for any further billing. But to my surprise after 15 days again I started getting mail stating that I have to pay a sum of Rs.545/- otherwise legal action will be taken. When I contacted them over phone no one was able to give proper reply and when I sent mail they mentioned that I have to sent mail only through my registered mail (that is company mail, which has been withdrawn by the company once I get retired) I explained them this but still they have not responded properly and now again I started getting calls from unknown persons stating they are lawyers and calling from Delhi and want me to pay or come to Delhi Court for case. This is very ridicules from the company and they are doing this intentionally, apart from this recently for the last one week one more sms is coming from them stating that I have to pay another 782/- immediately otherwise face legal action. This is too much and they want to run company by cheating customers. I want all the cases against me to be withdrawn immediately and proper action to be taken against this company and also I should get the refund of my earlier payment of Rs.1543/-.
