Makro online order not delivered

I baught a TV from Makro online thinking that it would be much easier than going to the store. The TV was supposed to be delivered on 29 November. On the way to delivery the courier unfortunately got involved in an accident (this is not my problem. Accidents do happen and they have my sympathy for that.) The courier company then informed me that they are going to take the tv to their head office to check if its been damaged. I then phoned Makro online call center and told them that I dont want a tv that's been opend and in an accident since I paid for a new one. The woman at the call centre then assured me that she changed my order from delivery to in store pick up. I then went to the store in Vanderbijl park to find out that the online call centre never advised them that I am coming to pick up my order. After about a hour the person at the store arranged for me to do the pick up. I went to the electronics department where the manager in the department told me that they are out of stock on the 55" uhd curved samsung tv's. He also said that the whole of South Africa is out of stock and that I would have to wait 22 days for an import. This was on Saturday. He also assured me that he will contact me today to confirm how long the order is going to take. He never phoned me back. Today the courier company pitched up at my house with the same tv that was in the accident. I told them to return the tv to makro since they arranged for an in store pick up. I have bought a lot of things online and I've never struggled like this before. I phoned the makro call center again today and they said they will sort it out and get back to me.
