Monro Muffler/Brake & Service Store manager tried weaseling out of mistakes made by his repairman Manchester Connecticut

I brought my vehicle in for a balancing to the Monro in Manchester, CT. When I went to pick up vehicle, the key broke off in the ignition because the repairman forced it out when he parked the car. When I told them of the problem, the repairman came out and started shoving a screwdriver in the ignition and completely killed it by forcing it back and forth. The vehicle had to sit all weekend in the shop and then on Monday they realized what they had done and tried denying it! The store manager was a weasel and tried offering free labor, but not parts. I had to go over his head to get the whole repair covered.
Now I have been getting the run-around while they keep the car. They promise me everyday that the work will be done and then nothing happens. I checked on my car one evening and found it outside and unlocked. I can't get a response from anybody at customer service and I still don't have my car back almost a week after I brought it in!
By the way, if you ever visit this shop, don't fall for the "front brakes need replacing" scam. I have been stuck in the store long enough now to watch the store manager give everybody the exact same speech, including me.
