More than two months to get car back

To say we got the worst service so far from Automagic Centurion will be an understatement. If we could give minus 1000 stars we would. But let's start with my fiancé's car has been with Automagic Centurion from the 21st of February 2022 for repairs. The initial estimated end repair date would have been the 23rd of March 2022. But then they notified us that the date has changed as the repairs on my fiancé's car is not complete and changed to the 4th of April 2022. We understood and, cause things happen and then when the 4th of April 2022 came, they contacted us yet again and changed the date to the 14th of April 2022 and stated they cut the one part wrong. Then they contacted my fiancé last week and said his car will be ready by the 26th of April 2022. They made countless excuses and blamed loadshedding for the delay. My fiancé then had enough and said he wants his car back by the 22nd of April 2022. 22nd of April 2022 came and went and Automagic Centurion contacted my fiancé again and promised his car will be ready by the 27th of April 2022. My fiancé told them are they open on a public holiday and they said no, they are closed and changed the date to the 28th of April 2022. We both tried to phone Automagic Centurion and they have been closed from Wednesday with the public holiday and only re-opening on the 3rd of May 2022. We have been from pillar to post regarding this and not at all happy. My fiancé had to go and get financing for a new car otherwise he would have no transport at all to get to work. So, this is totally unacceptable and unprofessional!
