Windshield Replacement

I am very unhappy with the service from MMG Mobile Glass. On August 16, I called them and asked for a quote for a new windshield for my van. They quoted me at $244 and promised no additional cost if I paid cash. I agreed and they came out that day. The technicians asked for water (which was fine, it was hot) and for a roll of paper towels (they don't bring their own supplies?). When I checked on them, my old windshield was in shatters as they tried to dislodge it. Then they asked if I wanted to buy a new seal for $40. I explained that I was quoted $244 and had only that amount of cash. They said they would just use the old one (I stupidly assumed that a new seal was included in the original quote). After they left and I paid them, I noticed that a piece of my window frame was broken off. Then, on a recent rainy day I realized that my windshield wipers were completely not working, which risked the life of me and my children as I had to sit until the rain stopped and I could see to get home. Then, when I called to inquire about these issues, I was told to call back in 5 days on a Wednesday. I called back that Wednesday, they said there were no technicians available and to call back the next day. I called back, and no technicians. Then I called back a third time and asked to speak to the supervisor about filing a complaint. The man on the phone told me it wasn't their responsibility that the windshield wipers weren't working. I asked for his name, he said Philip. I asked for a last name and who his supervisor was and he told me that he was deleting my file and hung up on me! I had to take my van to the dealership I bought it from and pay $60 for them to plug in the wipers that MMG Mobile Glass apparently unplugged. I was also told that the seal leaks water when they ran it through a car wash. This company performs shoddy work and I am very unhappy with their customer service and quality of work. Spend your money elsewhere.
