Disgusting service from Makro online orders

I am totally disgusted with the Makro Online order system. I placed an order on 23 November 2021, on 27 November 2021 I received notification that my order was packed and awaiting courier collection. The SLA states 3-7 days. I phoned up on 1 December to find out what is happening with my order as the status does not change and was informed that they will follow up and give me feedback, still waiting. I phoned again on 3 December with no further progress on order. I phoned once again today 6 December 2021 and again was told they are waiting for it to be delivered yet on my order it now all of sudden shows no stock of certain items. Disgusting service. I want my money back today, not tomorrow, today
