Disgusted with the Service

Worst experience ever. I did an online order 4 June 2020 within 7 days I went to pickup my order and it was not there. I went 3 more times 7 days apart from each other and still nothing. I was so angry and told the manger I will not be leaving without my product, he gave me another product from the floor, it was broken. I returned it and asked for my money back instead. This was on the 29 June 2020, we did the return and I was told the money will be in my account within 7 days. Seven days came and went and still no money in my account. All this time I'm the one calling and driving up and down to Makro to follow up on my order as well as my return. I called on the 13 July to find out about my refund as well as if Makro will reimburse me for this inconvenience. After several calls back and forth they finally find the problem and will refund me within 7 days again. I was told I will get R75 off a purchase of R600...what compensation is this. The refund I'm crying for is R599 , so I must use the same refund at Makro to get R75 off . What type of service is this. I'm crying with Makro over 1 month and this is what they say. Absolutely disgusted
