Still Waiting for a refund from Makro 6 weeks later?

On the 19th June 2020, I ordered and paid for some vacuum cleaner bags online with Makro, their website said that they had stock. On the 20th June 2020, I received an e-mail from Makro saying that my order had been cancelled as they had no stock of that item and that they would refund me my money. On the 25th June 2020, I received a "Refund Update" e-mail from Makro requesting my banking details, ID number and POP so that they could process my refund. I forwarded all of the requested information to Makro and after numerous telephone calls and e-mails to Makro's customer care center over the past 5 weeks, I have yet to receive my refund from Makro despite their e-mails and website stating that the refund could take up to 10-14 working days. Very poor service all around, I will not be ordering online at Makro again.
