Update:
Sir,
I found out after arriving at your shop regarding the parts. My inexperience in your industry and not knowing that you don't use special order filters does NOT excuse your unprofessionalism in your industry, which was to tell me over the phone to come in the morning and then proceed to tell me you had no room until next week once I arrived. That was false information and poor communication on top of a very rude demeanor. I sincerely hope you don't treat other people this way when they don't happen to know how things are done in your car shop.
