[Resolved]  BSNL recharge Voucher — voucher pending for 5 days

i am using Bsnl students suvidha connection for almost 1year.my number is [protected].5 days ago i bought a validity recharge coupon of 165 rupees.when i tried to recharge with the voucher i got a message that "network is busy please try later".when i tried after some time it said " vocher is pending".i did wait for abt 3 hours and then contacted bsnl customer care.they said please wait for another 6 hours, this may be due to our server problem etc..after waiting for 6 hours i tried to recharge again and again i got the same message that the voucher is pending.i registered a complained with the customer care and my complaint number was KL[protected].they asked me to wait for another 24 hours and try to recharge.this time also it dint worked..after waiting for 24hours i again contacted the customer care and every time they said my complaint is under consideration and wait for say 6hours..i contacted the customer care 6 times after waiting for the time specified.then when i contacted them for the seventh time they said your problem is solved and the complaint is marked as solved.please wait for another 6 hour and the recharge will be done.
but it didnt worked this time too...
then today morning i went to the customer care at statue trivandrum in person and contact the officer there, he took a photocopy of my voucher and said my problem will be solved today itself...but till now the problem persists and am not able to call my clients..
please do something...
