Inconsistency and false promises made by Makro

On 25 November 2024..I placed an order online and accidently ordered 3 Defy Electric stoves instead of 3 gas stoves. The following morning I went onto their chat platform and spoke to Dingaan who tried to assist ...but did not actually assisted in resolving my problem.I asked him if they could not change the order to 3 Cadac gas stoves.He told me thst they can not change from one supplier to another which did not make sense to me at all.He told me that he would escalated my request.After about an hour a lady named Memory phoned me and gave me a choice of two options...I accepted the option to cancel the order and explained to her that I needed the refund urgently as it wss for a Bed and Breakfast...I was told that it will take 7 to 14 days.I told her that I could not wait that long.Reply..would escalate.On Friday I got a message that my order for delivery was on its way...contacted Makro online once again and was told that cancellation was only done on the 28th and if delivery arrives I must just refuse delivery. I asked for the H/O of Makro's number to log a complaint. I called the H/O and spoke to a lady by name of Mphule who told me that she will refer it to management and will arrange for my refund to be done the same day 29th and will call me back. I tried calling back on the same day as I had no feedback from her.I tried calling H/O the whole day on the 2nd Dec 2024 and no one answered...what image does Makro H/O portray for not answering their phone. I once again called the online department and was told that my Refund is still awaiting approval and that they are a call centre and can only escalate on system I need my refund ASAP
