Still waiting for refund 2 months later

In December 2014 I paid customs fees for a package at the Goodwood branch. I tried to pay with a debit card but the machine was faulty and kept timing out. I was informed that even though it showed on my banking account it will be reversed. I then paid cash as I needed my package. I informed them a week later that the money has not been reversed. They then informed me that I needed to submit a bank statement which I did, this was in mid January. I want my money refunded to me asap.
