Terrible, *********** service

Booked the vehicle in for a service with Charmaine, asked that electronic side mirror adjustment switch be checked. At 10:18 am on 12/02, I returned a call to Charmaine, during this conversation she had informed me the fan belt on my car needed to be replaced, quoted me on the fan belt replacement as well as the service, she informed me the that side mirror switch was faulty and needed to be replaced, and it was covered, and order for the part was placed as they have no stock. When i collected my car,I settled the payment for the service and fan belt replacement. My car was not even washed. On Thursday the 18/02 at 12:47,I received a call from Charmaine informing me that the switch had arrived, and made a booking for Friday 19/02. I took my car in on 19th, booked it in with Jakes. At 12:41 I received a call from Charmaine, asked me if i have been quoted on the switch replacement. I responded no, as per the telephonic, conversation on the previous Friday, she had said the part was covered and only quoted me for the service and fan belt replacement. She then informed me that now the switch replacement is not covered and will cost about R2000. I told her not to replace the part.
