Tread quarters Ruined brand new tires with improper install Norfolk Virginia

 Took my car in to have 4 brand new tires installed mounted and balanced on rims. Took them 2 days to do the work. They called me to tell me they were having a hard time mounting the rear tires but that they would eventually get them mounted. They said the bead was difficult to get set properly and that they could not get enough pressure into the tire to set the bead because of a tpms sensor preventing high pressure to set the bead. After 2 days they finally called and said my car was ready. I picked up my car and took it for a test drive. First thing I noticed is that it shakes bad now and it didn't before coming from the rear of the car at about 70-80 mph. I checked the air pressure and one tire had over 150psi !!!!! I set the correct pressure and inspected the tire. I noticed a huge piece of metal right in the middle of the tire. It was a piece of metal shrapnel about 2 inches long and a quarter inch around. It was not sharp on the end after removing it which seemed odd that it would puncture the tire.. Also while pullingnit out a large amount of tire sealant came out as well... Which is also odd because I had just picked the car up and I didn't put any sealer in it. It would appear to me that they purposely had a hard time inflating the tire to set the bead and puncutered my tire on purpose to get a large amount of psi into the tire and then made it look like I ran over something by placing a large piece of metal in the tire. They left it over inflated. Also the balancing for the tires is the worst job I have ever seen these are high performance tires on 19 inch aluminum rims brand new tires and they have over 10 oz of weights on each tire. That is extremely excessive. This place is dishonest. They don't have the capability to perform quality work. They lack the tools and equipment to do things properly. They ruined my brand new tire and had me drive off with an extremely unsafe situation. They actually gave my car back for me to drive off with over 150 psi in the tire. I am very didsapointed and upset that they would do such intentional things and careless service. I spent over a thousand dollars for tires that now I have one and possibly two rear tires that are ruined. I'm not sure but the front tires could be ad well. All of then have excessive weights on the tires. This place is horrible they shouldn't be doing anything with tires. This place is like going to someone's back yard for service on your tires and all they have are some hand tools. You would get the same results by doing that. They will lie to you and send you off in an unsafe car. They should have said they couldn't do it and or paid to have a place do it properly and at this point they should replace my tire they intentionally destroyed by a place that actually had the proper equipment to do the work. Then when checking out to pay for the service they claim the printer was down and could not give me a receipt. How convienint that all the sudden was for them.... Bring a car in without problems leave with all types of problems and pay for it. If that's what you want then go to this dump hole for auto service.
