Ac and heating repair service near Fort Worth, TX

Just look what they did to this lady - I wouldn't trust them! http://dfw.cbslocal.com/2015/09/25/auto-shop-wont-return-single-mothers-car/

Flat rate for labor is $200.00 even if its an easy fix of $19.00 for a new thermostat. I took my car in on a Monday morning to get a professionals opinion as to why my car was overheating. I did not receive a call back until Friday at 4:30pm I immediately returned my missed call at 5pm, but they were already closed, WHICH their sign says they are open from 8:00am to 5:30pm. The following Monday a week after my car was dropped off I call back and ask for the DANNY what the issue is with my car, he did give me an estimate of $250.00 to replace the thermostat, NO WAY!!! Oreilly's has it in stock for $19.00. I told Danny, No don't fix it I'll be there to pick up my car. When i arrive at the shop two hours later (during my lunch break from work) he says there is a fee for $87.00 to put my car back together. ARE YOU KIDDING ME!!! Why am I being charged if no repairs where done to my car? Because it had to sit at his shop for a whole week before they can even look at it & they had to take it apart to find out why it was overheating....BULL! I had been a loyal customer since 2005, he had done major repairs to all my vehicle, so i knew his labor charge is $200.00, but to replace a simple thermostat, sorry i was not going to pay $250.00 when i can replace it myself. I asked nicely to waive the $87.00 since it wasn't my fault that my car was sitting there for a WHOLE week, he has a temper WATCH OUT!! he yelled at me said NO $87.00 and get your car out of here or $250.00 so we can fix it! I said to him fix it & please have it ready within the hour (I was there at 11:30am), he said NO I'll have it ready at 3:30pm, i said fine i will be here at 3pm. I go to pick up my car Danny says to me I was able to knock of $7.00...Thank you Danny & paid the bill.... YOU JUST LOST ONE LOYAL CUSTOMER TODAY!!!
