Bharat Sanchar Nigam Limited [BSNL] — Unnecessary deduction from my prepaid number.

Address:

635206

Respected sir, I am an old man aged aged 69 years. I am using a sim card purchased from BSNL.The number is [protected]. Most of the time i was using this sim number. I am a poor person. But BSNL deducts Rs 5 -00 once in two days.This morning [[protected]] i recharged for Rs 10-00, . Immediately after recharging this amount BSNL duducted Rs 5 -00. How can I use this number hereafter. I had asked BSNL not to deduct Rs 5 from my sim card but the do not bother.Regularly they are doing this mistake.
Kindly do the necessary action so that BSNL will not do this fault again.
