No Service from Europ Assistance SA -

I have been trying to get the geyser fixed since Sunday 29 August 2021 without success. Supplier 1 came out on Sunday replacing broken part with old part. After this there was no hot water. I had to call Europ Assistance again. Supplier 2 came out after 21:30 without a light to see what the problem was. Their reply was a new geyser had to be installed. The installation was arranged for Thursday at 14:00 which did not happen. I made arrangements for Friday at 8:00. Again it did not happen. Supplier only arrived after 9. It took them the whole Friday to install the geyser and when they left I was told that we should have hot water the next day. At 21:00 I discovered that the new geyser was leaking water. I called this in and supplier said they would come and fix it on Saturday and that 2 tubes were broken which they can only replace on Monday? Not sure why as tubes are available at Leroy Merlin? I have been on the call today since 7:00 without success. It is now 10:48 and 12 calls later still no success. My insurance is paid every month in full on time but I am not getting joy?
