the first time repair went well. He gave me 1 year warranty. It is not true. Second time the window broke, he told me that he is coming and fix for free. Just pay for the replacement switch. He did not say it would be another $150. What he told at the first repair was that I pay for the switch. After paying $300 and window broke again a week later, I called him several times.Not picking up the phone from my number. He didn't answer the phone. When he did finally, he hanged up on me soon after he recognized who I was. Paid $150 for the initial repair, another $150 for the second time. the window was working only a month. Not professional to handle the matter. 1 year warranty is a lie. what he said he would do is a lie.
