I booked the car in for a service at which time a mentioned a fault with the washer fluid light remaining constant
I received a call at around 1530 that my car was ready for collection and everything was done. When I arrived at the Watford showroom I was kept waiting for 43 minutes as my invoice was not ready. Finally when I drove off I noticed that the washer fluid light was still on. Heading back to the showroom I was then informed that a part was needed and i would be contacted in 2 days and my car will be picked up and the needful done. I DID NOT HEAR FROM THEM FOR 12 DAYS. When I went back to the showroom utterly frustrated was told that no part was ordered. The manager Jacob who was suppose to have called me did not even have the courtesy to come and see me.
The assistant manager then ordered the part and booked me in today 6th Nov. For fitting the new part.
This is totally unacceptable and will have to think twice about getting a Jaguar when my lease comes for renewal.
