Vodafone India — money not refunded

Recharged for unlimited callswith rs 299, but on immediate next day i asked customer care executive to deactivate it as rs 299 is not for unlimited calls, at that they said yes. On the same day i recharged for another 295 for unlimted calls. After 4 days i asked executives to add the deactivated amount to main balance, on that day they agreed to refund, also told that i can use it whenever i need. But after 28 days they said money is not in main balance. Unnecessarily 299 is lost. I request please refund the amount from the vodafone.
