Mr Price Online, Pargo Pick Up Point

I made a Mr Price online order on the 1st of august 2022 with order number #***. I chose Pargo Pick Up Point as a shipping method. On the 5th of August I received an email and sms notification informing me that my parcel was ready for collection at Sasol Mafikeng. I also received parcel number OF******* together with a pin for collection. I went to the pickup point and couldn't collect because I kept receiving an error message that the pin was incorrect. I called customer service and was told that the parcel would be sent back and that I will be refunded. I received no refund and contacted customer services multiple times with no luck. The last time I contacted them I was told that I will be refunded within 7 working days. To this day I haven't received my money. I want my R809.99 back. I'm very disappointed to say the least
