Avoid buying online with Makro at all costs!!No replies and No accountability

I placed an order for a computer component on 13 June 2020. I kept tracking the order on the website which indicated the item was waiting at the depot for a courier to pick it up, I decided to call their Makro online support number on the 25 of June as nothing appeared to be happening with my order, After 29 min the call was eventually answered. I was told the same information and that my case would be escalated and somebody would call me back within 48 hours,,,,,By the 30th of June I had no answer I called again and was told the same story. I wrote an email to the support centre explaining the same and got an automated reply. I phoned again today 7/8/20 and was told that a Wandile from Market Place was at lunch till 2.00 and she would phone back with an answer by 3.00Pm. I phoned again at 3.30 and was told that Wandile was in another department but the case has again been escalated this was after waiting another 20 min and 30 min respectively for my calls to be answered . I asked to speak to a supervisor and was put on hold for 44 Min and then cut off (the line just went dead.)I have phoned back another twice and the line was cut off before being answered. How to I cancel my order or get anybody to take responsibility. Makro had a good reputation and I had ordered things from them before and got good service till a couple of years ago. What happened ? Avoid buying online its a disaster!!
