Main Muffler & Brakes

I stopped in months ago to get pricing on exhaust work for an older ford truck, I was told they would have to do some research and would call me the following MondayNo problem
After not receiving a call, I stopped back in that Wednesday, I was told they were unable to find time to do it so far and was promised I would be contacted by the end if the week
I'm still waiting
Not only have they not called me, but even a phone call when the first deadline had passed, should have been made
