Car taking long to be fixed

I had an issue with the car locking gears, i then took it into VW midrand and was told that they replaced the clutch this was on the 7th dec 2023. On the 21st dec 2023 while on my way to limpopo the car stopped moving it did not read gears the cars was towed to VW Wonderboom PTA and i was told my clutch is wornout which does not make sense that it could be damaged within 2 weeks after "replacement" . since then no one called to give me an update , i called on the 22nd dec 2023 they told me the car was in the queue. again they were quiet i called on the 28th dec they said they dont do repairs on sat and again on the 2nd jan 2024 and i was told Zack will call me back but he did not, on the 3rd i called again and i was told that the job card was transfered to Tony because Zack was not there the i spoke to Tony and he told me that i need to pay R18000 becuause the car warrantee expried on the 31-12-2023, i called VW SA to check and i was told the warantee will expire 31-12-2024, i called to notify them and asked what ecxactly is the reason my car is not being fixed i could not get an answer,i laid a complaine with VW SA on the 4th and on the 9th the call centre lady i laid a complain with from VW SA called and told me they have not done anything becuase they are waiting for my authorization, i told her am not going to authorize a repair that is under warrantee for me to pay R18000 she said she will i gect back to meo on the wednesday 9th jan 2024. Today is the 10th of jan 2024 my car has not been fixed and no one is updating me of anything both WV SA nor Vw Wonderboom.
