Best Generator Hookup in Houston TX

I was referred fo them by family ! He had a great experience with a single electrician who came and got the job done ! I got sent a team of 3, the lead lied about how the outlet needs to go over the roof and gave an unrealistic fake situation to over charge us. Tried reaching out to the owner and help desk to hear various excuses ! Charging 1700$ for installing a Tesla wall plug which costs $400 is outrageous! They ended connecting using a 8ft cord but quoted us a 50 ft quote ! Will try this method and will be reaching out to Texas licensing authority in Austin !
