Unsubscribe phone back up

Dear sir, I had already subscribed PHONE BACKUP SERVICE. Now I want to unsubscribe it.

I send SMS of UNSUB at 58989 MANY TIMES But I receive no confirmation SMS. EVERY MONTH 30 RS. LESS IN MY BALANCE.

PLZ SIR DO SOMETHING urgently. HOW CAN I DEACTIVATE THE PHONE BACKUP SERVICE??
