Patiently waiting, and loosing customers

I have been waiting since the beginning of last week.. almost 10 days now for a window to be put in in my shop facing the road. My shop has been in disarray for this whole time now. They never called me last week to cancel.. they just didn't show up. I finally moved stuff back around on Monday so that I could work in there again.... then I called them Monday and Tuesday to ask when it was going to be put in.. on Wednesday he called me and said that he was on his way around 1pm. I waiting till 3:30 when he called and postponed again for tommorow! This is really ticking me off. I've had to move my whole front office around to compensate for them, and then yesterday I had to shut down the shop and tarp everything up... move what was needed to be moved.. ya know?! I mean, I'm loosing business while I'm being pushed around! If this building wasn't created by them in the first place then I would have already had someone else do it (for a cheaper price too!) I just wanted to comment on the level of service from some people here in Crossville. I hear this all the time from my clients who are upset because of another technician or business toying with them... rescheduling, or just not showing up at all. I am sorry guys! I promise I try my best to not be like that at CGrafiks!
