bad service, zero quality

I own Volvo for 5 years in Ottawa and unfortunately from time to time I have to bring a car for service to Volvo. It is the worst auto service I have ever seen. Customer service is zero, they will never call you back if you ask them something. Service is expensive, poor and slow. In few cases I had to bring the car back on the next day after the service. Once I complained to Volvo Canada and Volvo Canada have not found anything better than answering that Volvo Ottawa is independent entity - so Volvo Canada does not care what service Volvo Ottawa offers. As soon as I will sell my Volvo I will never buy another one and never will come to Volvo Ottawa.
