Poor customer service

I have been waiting for a part for a Genesis Cyclovac for nearly two weeks now. The Verimark Newmarket store assured me the part would arrive last Tuesday. They promised to call me, but never did. When I followed up they told me it would be available today. Again, they promised to call me but never did. I just phoned now and they said they don't have the part and don't know when it will arrive - very poor customer service. The only helpful person has been Patricia from customer care, she phoned me and sent an email to the store last week instructing them to order the part and to call me when it arrives. It just seems that this branch does not take customer service seriously. I do not wish to deal with the Newmarket branch again, as their incompetence is very frustrating. Please let me know which nearby branch stocks part no. 80GCV1006, and when it will be available for collection.
