Refund pending after 3 months

I orderd blinds online from Makro in January. After it was first dispatched to the wrong address, I received blinds that was not matching in colour and was damaged. I send it back to Makro, requiring a refund. The return process was also with a huge struggle. On the 6th of February I made my first telephonic enquiry regarding my refund, followed up again on the 3rd of April as they say it can take up to 6 weeks. On the 16th of May, I still haven't received a refund for a purchase of over R3,000.00 Every time I must hear that they are expiditing the refund just to receive no refund back. Are they *****ing the money or what is going on? I cannot recommend Makro to anyone. I will rather pay more at another company with reliable serivices
