Allahabad Bank — refund of money

I have been trying to contact allahabad bank for refund of money since 2 days but everytime the number is busy. I have mailed the bank authorities for refund of money but no reply has come from their side. It is creating a bad reputation on the customers. Please resolve this issue or else i have to take this to the higher authority. If nothing will happen then i have to take action against the bank authorities.
