Panco Garage

So I take my car to Panco about 2 weeks ago. The mechanic tells me its my timing belt. I was like wow my car just stopped working after I parked it, and their telling me it's my timing belt? I asked the mechanic did he run any test and he said he could see that the timing belt was loose. I asked if he could run a compression test to check the engine and he said a compression test is not a way to determine if I needed a new timing belt. To make a long story short he ended up pulling the timing belt off the car, and then he said it might be your engine, I was like ????. I took it to another mechanic and they were shocked by the timing belt being off the car and not put back on, further more my mechanic stated that the timing belt couldn't have been the problem. Panco took a guess on my car and ruined my engine. I will never go there again not even if I have to put air in my tires. They suck
