BSNL — Unauthorised deduction of balance from cell phones account

Address:

Lucknow, Uttar Pradesh

I am a Bsnl wireless prepaid cellular service customer...From last 2 months at various incidences a charge of either Rs5/- or Rs10/- or Rs20/- is deducted from my account for different services which are not requested by me.
As soon as i recharge my account the amount is deducted within3-4 days..leaving the balance to either Rs1 or Rs2.
During the duration of last 2 months atleast 6-7 times my balance is deducted in a similar fashion.Each time i have registered a complaint on customer care of bsnl. At each instance they have either assured me that such deduction will not happen in future or my balance will be refunded..but none has happened so far..Last 2 deduction of rs 5/- each have happened on 22 October 2012 and 21 October 2012.
At each complaint registration i was given a docket number...some of such docket number are-- J21UE306321; I10UE307936; H10UE302938.
So far there have been no positive response from bsnl...Expecting for a quick and immediate action on the issue from the forum.
