My acct. is charged but service not provided

I have choose a dialer tone, and send sms to activation but after i have pay 30 Rs acc. to terms my tone option could not activated (at the time of apply this facility my a/c bal is Rs 30.44 Ps) and after that they send sms me my activation has been cancelled due insufficient balance, its ok but why my acct. is charged to rs 30, if my activation is being failed. Beware!
