Business ProfileforQmerit

I purchased a lyriq and was told gm is offering $1500 for installation and I thought is was going to be smooth transaction. I had called three independent electric companies I had did research on because I wanted to protect my house and others and my brand new truck so just like qmerit. I made sure they were licensed and bonded and it they would pull a premit to do the work and I also read reviews on them. I was quoted $600-$900 from my independent electricians who all came to my house. This was part of the reason I decided to purchase my truck. Once I got my truck qmerit was notified and I got a quote around $1900 from an electrician that didn't even come to inspect or answer any of my questions. 2nd quote comes from a guy who wasn't and even a license ************************* who told me he wasn't license could not answer my question about if my breaker box could hold the load of the ev. His quote was around $1700. I contracted qmerit to see about a ************** and the rep basically ignore my request for a ************** by telling me the second company lowered their price and all I would have to pay is $94 out of pocket. I shouldn't be paying anything out of pocket. The rep isn't listen to me and is basically trying to make me choose the second one. Why are the prices of qmerit so inflated? Even on online it says $600-$1000 to install a line.
