You have complained to customer care.Have they issued you a unique docket number.The company sends SMS also after the call of customer ,giving the docket number.
If not you may:
-give reference of your call,and quote date time the name of CCE who attended your call,and ask to supply you the docket number.You may mention no SMS was sent, and if the company wishes to claim they have sent the SMS ask them to send again.
-you may escalate the complaint in writing to Nodal Officer, asking for docket number and confirmation in writing , on which date they have terminated the connection, and by which date they shall refund the security amount to you.You may confirm your addrss again and ask to supply them a letter byr egistered post and may state if they wish you are willing to sbmit a postage pre paid, self addressed envelope.
You may ask for a finall bill upto the date of your request for disconnection.The company may deduct the bill amount from security(+late fee) if you don't pay the bill.The time limit for refund of security has been prescribed by TRAI.
