Poor online ordering systems and Delays!

I ordered 3 appliances online from Makro, a Dishwasher (urgent as mine broke down), an Oven (it also packed up same day as washing machine and a dishwasher (not urgent). I ordered online as it saves me driving from store to store to see who has stock. All 3 these items were in stock in at least 6 stores in Gauteng when I placed the order. Online guys allocated all 3 orders (these were separate orders by design) to 1 store, Silver Lakes who only had 1 out of the 3 items in Store (the dishwasher) - after 3 days Silver Lakes calls me and says they do not have stock of the other 2 item, I must cancel the online order wait for a refund (48hrs ) and then order other items - this is unacceptable - I called the online hotline - asked them to allocate the orders to one of the stores that has stock - or alternatively allow me to find a replacement item that is in stock at Silver Lakes. After 2 hrs on the phone neither option seems possible - and the query was escalated!- The person on the line could not tell me when the escalation will be responded to (it could be weeks from now for all I know) - these 3 items were supposed to be delivered this Friday - I may get the dishwasher but not the other 2 - Makro is in the mean time sitting with my money in their bank account holding me hostage - I can not swop the items and have to wait for Silver Lakes to source the items - this may take weeks - they blame the Corona Virus for the stock levels - both are Bosch products (made in Turkey/Romania) so highly unlikely! Even now when I check the online store all 3 items seems to be in stock at several Gauteng stores!!!
