Terrible overall experience

@ DCP I was almost ******ed by katy & a manager been told I was miss quoted & they HAVE to spray my fender to blend it in,consider i brought my car to respray my bumper. After 10 minutes of back & forth i said i would take my car somewhere else. The 2 discussed privately & agreed to fix my car. After 9 DAYS of my car been in the shop for ONLY A BUMPER respray. I collected my car, at home i was about to wax my car but felt roughness on it. Called a spray painter friend of mine he confirmed my suspicions of over spray. I emailed katy immediately. Recieved a email from katy saying that it could not be overspray,my car was not in spray booth & was covered. @ DCP it got ugly very fast with talk of managers and directors down my throat. A manager an paint tech came to see the car and denied DCP involment. I asked for a walk through an found that none of the cars that were near the spray booth was covered. Still heated i asked to see video footage only then did they agree to fixing up my car. A few days now i took my car to wash and found theres swirl marks from the machine.How does a QC allow a car to leave like that & my fender was not blended. I have emailed Wayne aswell no response.
