Claim for Refund

I have paid a deposit of R1500.00 for a windscreen at PG Glass in Centurion. I later cancelled the order due to the fact that my insurance was going to pay for the windscreen. I was then given a Refund Request form to complete and submit in order to process my claim for refund. I was told it will take 5 to 10 days to process, but now 22 days has passed but there is no refund nor feedback from PG Glass regarding my refund. I tried to send emails and called their office but no luck and my calls go answered. The claim was submitted on the 29 February 2016 but hasn't been any feedback.
