IS Trariff plan activated if already another activate

Dear Sir,
Yesterday, I recharge my mobile (prepaid ) bsnl with 225 tarif plan While a plan 100 for two month already activate in my mobile number, but this card not activate in my no. When I checked my tarif status (*121#), result outcome "you subcribe to serviceclass 2015 until Aug 10".
The my query are?
1 This card used to another mobile no (When talk customer care the response there were not activate any type of tariff on after 7 june, 2008) i.e. more than one month.
2. This tariff will auto activate after first end.
3. Is I had been charge such amount without and services used of bsnl (for which activate it)

HI Sarkar, welcome to eTI..

Actually its not clear what you are trying to ask..
What I get is that, you tried to recharge your BSNL prepaid with 225 tariff card but it does not work as you already have Rs. 100 tariff working and will expire in two months ?

Is that so ?
