Maaco Franchise

I don't know where to start. I am not a writer so bear with me. Paint on the windows, carpet, inside the doors, tires (driver front and rear), wheel wells, brake caliper (driver front) and for the life of me I can't figure out how the door sill trim got cracked it must have been hit with something.
This is a 1996 BMW Z3 painted at 1650 Silas Creek Pkwy in Winston Salem, NC. [protected] The project was wrote up by Alex Mabe. The job was to install an after-market bumper cover, address the driver side door for a dent and paint the car. I delivered the car on 1/15/2016. After 2 weeks or so (02/02/2016) I decided to call to see what was going on since I hadn't heard a word. I talked to Alex and enquired on the progress of the vehicle.
Alex said that he had called me 2 or 3 times to let me know the vehicle was ready. I never received a call from Alex. I asked him if he had left a message; Alex stated that with the type of phone that he had he was incapable of leaving a voice message………. WHAT the hell is that? At that point I knew something was wrong. Alex said that the car had been ready for a few days. I asked him about the bumper cover and he said that it was ready for pick up. I told him fine I would be there shortly. I live about 20 minutes away. I arrive at MAACO and see the car. The bumper cover was hanging off of the front of the car and had been PAINTED! I head inside to talk to Alex and the owner informed me that he had sent Alex home sick and that he would take care of the matter. So I informed the owner that I had just talked to Alex 20 minutes ago and he told me the car was ready for pickup. The owner explained to me how they tried everything to get the bumper cover on and that they could not do it. So why did you paint it? He blew up told me my vehicle was a piece of a crap only because he couldn't install the bumper cover. I did not deserve this. I did nothing wrong.
When it came to the point that there was nothing else that could be done all work should have ceased and I should have been contacted IMMEDIATELEY it never happened. Now I have to find someone else to install the bumper cover hope and pray it can be done without a respray, clean the carpets, fix the cracked sill trim and clean the paint off my tires, windows and brake caliper.
This was by far the most unprofessional service I have ever had. I have had vehicles painted by MAACO before and never experienced such rude and disrespectful individuals in my life. I'm 59 years old.
If you guys condone this type of behavior it is really sad. I did nothing to deserve this. If you guys don't want people of color in your establishment just put up a sign. This is the only reason I can come up with for this treatment. I did not deserve this……
