[Resolved]  Prepaid Connection — Magic voucher

I am having prepaid connection of bsnl([protected]). I have recharged with Rs:300/- magic voucher which is ment for unlimited calls to bsnl nos for 30 days. After 4 days to make the the 1 second billing to other operator nos, I have recharged with Rs:50/-. Now my earlier plan for 300 is ineffective and my calls to bsnl nos is chargeable. Since the 1 sec billing is for 1 year validity and its scope is wider it should be allowed to use both schemes together. Moreover its not mentioned in the recharge coupon the these two should not be used together. This is some limitation due to technical reasons and is misleading the public.
The response from the bsnl customer care is also very bad.
Since the people are paying whatever amount the bsnl is charging they should be allowed to use the their service without fear of hidden cheating technics.
