Refund not received for counterfeit goods.

I purchased an HP battery from the Makro Online Marketplace which turned out to be counterfeit. I logged a return and it was collected the following day. On 3 June I was told that my refund had been approved and processed. There's still no sign of said refund in my account. I've now been told to wait another week and contact them again if I haven't received my refund. There's no reason for a refund to take 2 weeks regardless of supposed banking delays. My online profile still shows absolutely nothing. Still just stated "Return in Progress" as it did when I logged the return.
