Cancellation PROBLEM

I've accidentally ordered an incorrect appliance from Makro online on 16/11/2023 and my 1st payment from Payflex went off. Then, when I received my Invoice on email I realised my mistake and I immediately phoned Makro Online 16/11/2023 to cancel the order. Spoke to Keith and he was very helpful and gave me my cancellation ref nr and also said and agent from cancellations department will phone me to confirm. Nothing for 2 hrs. Phoned again 16/11/2023 spoke to another agent and he confirmed that cancellation was logged but that I should wait for cancellations dept. Nothing. Phoned again on 17/11/2023 @ 08:00 spoke to Mahle, very nice person and escalated my query. Nothing. Courier company in the meantime phoned me to confirm address for delivery on 17/11/2023 @ 17:06 as to which I then told them the order was cancelled and they need to take appliance back to Makro. He was very nice and confirmed he will go back to Makro. Phoned again on 18/11/2023 spoke to Bulekele (no lt sure of spelling) who also escalated the query as urgent. Also send a message on X and I received a reply that they will also escalate. Nothing. The predicament is that Makro Online needs to press a simple cancellation button so that the cancellation can go through in order for payflex to reverse my payment (as already discussed with them) in order for me to order a new washing machine that I so desperately need. In the meantime I'm paying for a laundry company to assist because Makro Online is to *********** to press a keyboard button and to cancel the order. This is not rocket science. Just phone me to confirm the cancellation so that the payflex payment can be reversed so that I can order a new washing machine. Really, really. Pathetic to say the least. Come management, show your worth.
