Mts — Asking me to pay for the bill which I have not used (my usage is 0)

Address:

Chennai, Tamil Nadu

In Dec month I have received the call from MTS regarding my payment and I asked them to give me a confirmation for closing the account. They gave assurance and made me to pay bill Rs.688. On the bill, the executive from Sistema Shyam Teleservices Ltd written that 'Line Deactivated' and 'Bill Closed'. Please check the attachment. And now from MTS saying that we cannot accept this as proof (very unprofessional that they cannot accept this as proof which is written and signed by their executive) and asking me to submit any mails that stating that I have requested for disconnection (I have uploaded that mail as well please check) and any recorded voice. Think that how can I record their call (so beware of MTS and guys ensure to turn-on your voice recorder before calling MTS. If you do not have a small phone then they will not accept any proof even which is written by their executive and the mails that you send.). It is really cruel that asking people to pay which they were not used. Please someone help me. Thanks, Subathra G
