M & M Appliance

I called M & M Appliances on 4/17/2015 around 8:15 am to see if they could come out and fix my AC in my condo in Galveston. I had guests staying in the condo for the weekend. The lady I spoke to assured me that a technician would be out between 1pm and 4pm same day. At 4:25pm they still hadn't shown up so I called because I knew they closed at 5 and the night before I tried to call them and the phone just rings, there is no answering machine of after hours service. The lady that answered the phone at 4:25 said "oh yes they will be out there, they are just running late honey". I asked if she could please give me the technician's cell phone so I may reach him to find out what time and she said "that's not necessary honey, I assure you they will be out today". After my guests had waited all day and till around 6:30pm, they called me and told me that the techs still hadn't shown up. Therefore I had to hire an emergency A/C contractor to go out and fix the AC on Saturday at cost of $290 and also had to relocate my guests to another condo for Friday night at a cost of $348. If M & M would have called this morning to tell me they forgot or something else came up, I probably would have been ok about it, but it concerns me when a contractor out right lies about something like this. What else are they lying about?
