Bumper change

This business is run by dishonest people. They gave me an estimate in writing and lowered it down for cash money( red flag ) . I dropped off my car and the next morning I got a call saying that I am suppose to bring the part to be installed which wasn't true and wasn't on the estimate. I asked to speak to the owner Rick who was extremely rude from the minute he came on the phone and I told him that the estimate stating the part is included with $6.25 % tax. He claimed that this is just paint and the waste charge. At this point I said "are you charging me tax on wasting?" He got very defensive and asked me to pick up my car. I was so happy to pick up my car not fixed by people like him and his unprofessional, dishonest, liars staff. I don't recommend this business to my enemy.
