MTS / Sistema Shyam TeleServices [SSTL] — Mts data card deactivation

This is regarding my data card connection with mts - MDN no: [protected]. I deactivated the account in the month of September however the mts store in mugappair did not close my connection. As a result my connection was still active and I was charged for another month.
I logged multiple complaints through customer care however none of the complaints were resolved and they closed all my complaints
I then went to the mts store in mugappair looking to find a resolution. They did accept that it was their fault and they will waive the pending 733 that was due.
I thought my issue was resolved when to my shock I received a threatening call from a lawyer representing mts. They demanded payment and were not willing to listen to my explanation.
I then went to the store again and the lady there assured me that she has sent the mail regarding my waiver to the respective department and the issue will be resolved. She also gave me a personal number to call her for any issues relating to my complaint.
I thought that finally this has come to an end when I received messages from mts to state that legal action has been taken. I called the lady and she again told me that the issue was resolved from her end and that she will stop these messages.
But till date I am getting these messages and today they have served a legal notice against me.
I tried calling that lady but she refused to attend my calls.
I am at my wits end as I don't know where to go and how to sort this.
I, as a consumer demand that my complaint is looked into immediately. I have been treated badly and put through undue stress. This has impacted my work and family life.
