Idea Cellular — bill received after connection closed

Address:

New Delhi, Delhi

Dear Sir, I was using a idea postpaid number [protected] but due to no usage i have request to idea customer care to close this connection permanently on 02.06.14 and they replied me on 03.06.14 vide SR#C1-[protected] that the said connection has been closed. Bill dated 17.06.14 for Rs.807.25 has been paid in full. But after this they send me the bill on regular basis every month. When i informed them that the connection has been closed they why are you raising the bills then they told me that they are looking into the matter and will be resolved soon but till date (31.03.15) no solution has been provided by them.Last bill generated by them dated 17.03.15 for Rs.1375.30 (includes previous dues which was never used by me.) Request you kindly look into the matter.
