Refund rejected since February

January I returned a plastic pool for a refund. I was told to exchange for I need to purchase something at the till so I bought dewormer for my dogs. We got hoke the box was empty I contacted Makro for a refund but my car was sent for repairs so they agreed to collect the box from as I mentioned it would cost me more to Uber there than the actual product.

Later on I was unable to drive for the refund, I was highly pregnant. I asked for weeks for them to send the credit to the house. Customer service said I needed to come in. I mentioned countless I am highly pregnant Uber will cost than the product and I didn't need anything from makro. It's now 5 months later no one bothered reaching out since. I went into labour sooner than expected and moved to the westrand now. How do I get my money back for the product I didn't receive?
