Virgin Service Provider — Unable to access the free message facility after making a recharge of message voucher

Address:

Chhatarpur, Madhya Pradesh

Sir,
I am using Virgin sim. Mobile no.is [protected]. I made a Special Terrif Voucher(STV) recharge of rs.64 for availing the facility of free sms on 3rd April 2013. After making the recharge i got a message saying "Hi! STV Recharge Successful. MRP Rs.64, Validity:30 days, 100 SMS/day Tranc ID: [protected]".
I still don't have access to this free sms facility. I made a phone to it's costumer care on 4th april. They told me to wait for 8 hours. After waiting the sms didn't get free, i phoned them again. They again assured me that i will get access of free sms facility after another 8 hours. Five days are passed but i still don't get my problem solved.
