Worst dealer - I left my car on Friday afternoon with main priority being to fix the2 key fobs. I had also also requested the service department to check AC and breaks and come back to me
However all they did was check and advice me what I already advised, and charged me $330 for diagnosis
I rang at 3pm on Monday afternoon to check if Volvo xc90is ready to pick up. .The service department
came to me after 20 minutes and told me that to fix ac will cost me$2227.00, ,so i told him that i need the car. After couple of week I rang to book for reprogramme of fobs and I ask the service department if they have reprogrammed the computer system which I thought DIAGNOSIS was reprogramming was diagnosis and charged me $330.
