Service Turns out to Nightmare for awaiting Waterpump (Isuzu - City Deep)

Booked my vehicle in for service by you on Wednesday, 12th January 2021 as per the usual annual service as I never reach 15000 km’s. Later afternoon I Was called and told there is a leak on the water pump. This to me was and still is questionable as my car has not even done 70 00 km’s and besides did not use any water and no water marks in my garage. However I still gave my maintenance policy details for repairs which was authorised. The problem her now is that apparently the part was supposed to arrive on Friday, 14th January 2021 but did not. Then suppose to be at your dealership this morning at 08h00 and also not. The service advisor called me and told me so. So being without my vehicle for 6 days and going into a 7th day ?? This is unacceptable, This whole country is a mess with no Customer Service at all. I pray that I never dissapoint a client like this as our clients pays my salary.........
