precision garage door repair Precision Door Services broken my garage and left. san mateo, California

My right side of garage door cable got loose; Precision Garage Repair came in November last month fixed the Right garage door. By 12/29/11 my Left door cable got loose; I called precision again, after secretary set the appt. a man from precision called told me I need new garage door.  Immediately I feel fishing, but too late to stop them, he moved my appt in one hour. 

The repairman came over, and he keeping talking and run the meter, and then charged me $385 to fix loose cable on the left  garage door,  and stated that the fixed R side garage has the wheel a little parted, i told him it was fixed by his shop little over a month ago, and i negotiate price to $175.  He was mad like hell, he told us get out of the garage, and all this time he stayed in the garage by himself and will not allow us in the garage. 

The garage was dark; I dont know what he is doing.  After he finished the job.  I went out, when I returned around 11:30pm, I can't open the garage, I called the cop, they came around 1:20am midnight opened the garage.  Next morning Friday,  I need go out in the morning, the garage got stuck can't open. I called the Precision filed complaint.  I wait for another hour or so before I can finally got my garage open and went out,

upon my return around 2:30pm, the garage stuck again, the same repairman came by, mad like hell, and told me I need new motor, I said my right side of the garage (two car garage with separate garage doors and separate openers) worked perfectly that is until you mass around my garage doors.  I called his boss, he said you need to pay for new motor replaced, I said you came to fix the left garage door, and mass with my right garage door, it was working, after you mass around, it is not working any more.

He said I only listen to my repairman, that you need new motor, that costs you $400+, I said you can't come in broken my right side of garage which was fixed by your worker last month. And have me paid for the damage done by your worker.  Last month the Precision other repair man told me,  that my right door motor have no problem. I believe this is retaliation,  because I dont believe fix the left door loose cable costs $385.00 as the repair man coded me. 

I did not pay them the unreasonable, hijack price fixing left door  loose cable.  The same repairman returned this afternoon,  and he checked my R door motor in one minute, removed the cover and put the cover back, and said you need new motor, and wanted charge me $400+ for a  motor is not broken. And the repairman just left my garage broken non-operable and took off and refused to make my right garage door working upon my repeated requests.

Only stayed in 5 minutes. When I told him that the cop came by opened my garage last midnight, he said why you called the police for?  I told him that police told me that the little button is too greasy and move back and forward, because he spread my WD40 heavily on the Right door motor, and he said why dont you have the police fix your garage?
