Electrical A-Z Contractor

The provider Fred was very pushy with his communication and even said "Do you want us to cancel the job) when it took me a week to review his quote. He showed up at our house without warning and when I was trying to get downstairs with a mask, he just opened our front door and exposed my unmasked daughter. He asked if we wanted 2 switches fixed and we said fine, but then forgot to install them. He found out that I was a registered engineer and would not leave me allow personally. He sent several rude emails claiming that we damaged his van and I had to report it to our insurance. The I told him that our home insurance does not cover cars parked on a separate street, he help me receipt "hostage" and blamed misconnected wires on us when that was the entire reason we hired him. I told him that he was acting unprofessional and he said the same to me and told me that my review didn't matter because I am not a logical person, I have a BS in engineering and work on multimillion dollar jobs, so that was not only rude, but untrue, We have had to put a claim on our final check because we are going to have to pay other contractor to do what Fred claimed he could. I even asked him if he repair included circuit or wiring replacement and he said yes, but that was not true. Even the home warranty investigators said that his costs were high, but we needed work do. I feel that all of his interactions with me have been condescending and trying to get money out of me that they don't deserve.
