no good customer service from menlyn

on the 27 of october 2020 i towed my car to vw menlyn because of clutch problems. they notified me that they will start attending the issue in the next 48 hours. on thursday i received a call which i was notified that they need to remove a gearbox to check the problem and it will cost about 6500 to remove the gearbox, i agreed to proceed. on friday the 30th October 2020 the warranty paid the full amount including the parts and vw called me back to notify me that they have to order the clutch which may be available on wednesday the 04th of november 2020. on the o5th i called them and i was sent from pillar to post and eventually the parts department told me that the clutch has not arrived. it is the 10th today and still no response from vw menlyn and they keep on giving me false timeframes which i do not understand plus they refused to provide me the curtesy car stating that im out of service plan. i do not understand because my warranty has already paid and the delayed of parts is their concern
