power steering,change alternator

about 1 month ago i took my car to george at full throttle because there was a growling noise under the hood,I was told that it was the power steering pump i paid to have the pump changed and my car was still making the noise,george the owner said to drive the car to see if the noise gets worse so i drove it for about a week and the noise became worse so i took the car back,a pulley had broke and it was to the alternator i paid to have the alternator replaced,the noise went away but the car was making a chirping sound like there was a bunch of birds under the hood,we also noticed that the trunk and gas door would not open,we took the car a 1997 caddilac seville sls to another mechanic and low and behold he discovered the damage that full throttle had done,we have replaced 3 belts on the engine and they all keep shredding,i had the tenisioner replaced also after going to full throttle i have spent 390.00 in parts and labor and the mechanic is still trying to figure out what other damage was done. This is the second incident i have had with george and his fake mechanicsI had a ford expedition that i took there to have the brakes changed my family and i sat in that dank bussiness for 2 hours waiting for the job to be done they never changed my brake pads i went to another place tp have my brakes done about 3 weeks later only to be shown my old brake pads were never changed. beware of this place they are ripping people off and should be closed down they ruined my car and its costing me over 1200.00 that i dont have in repairs
