Product: Payday loan, title loan, or personal loan

I had a salesman come to my house from a advertisement I saw on XXXX. Basically it said go solar and save money. Our electric bill had been going up alot in the last year since it changed from XXXX to XXXX. So I decided to check it out. He told my wife and I that he was positive we cc old same lots of money and own our own power and have a backup battery when their was outtages. I stopped him before he went into his big sales speech and I told him that this was all strictly about saving money and I didn't care about all the other stuff. So he asked how much I payed for electric and I said what is the monthly fee on this solar program. And he told me about XXXX a month for 25 years. So I said if we can do that then give me all the info. So he told us they would put 18 panels on our house and because we have no trees we would never have to pay electric bills again because the electric company would have to pay us for all the electricity we send back to them. He said this system would cost {$70.00} dollars but since we were buying now the government incentive would pay {$20.00} of that. And that they ( XXXXe ) ( XXXX XXXX ) would pay for our first twelve months bill. Also it would be completely covered while we pay on it by them battery was only 10 years. And after we throughly went over everything and the payments went up to XXXX but he said I could pay some more cash after the first year of making no electric payments and lower my bill. It was installed the beginning of XXXX and it has never worked!! I called and called them and sit on hold for hours and when I did get someone they tried to tell me that it was working and the checks in the mail for my first 12 months payments?? Then I XXXX they admitted that it was not working and said they were going to send someone out. Meanwhile I have been making payments on both the solar panels and to XXXX for my electricity. Goodleap is our finance company. They have been rude from the beginning! The sales didn't leave us any paperwork! I had to sign on his computer for all of it and he said he downloaded it to me while he was here but it never got to me so he said it would be in my email soon. I never got it so I was talking to the arbitrator that goodleap assigned to me and she sent them to me. She told me that she read in my paperwork that after 18 months the payments go up to {$450.00} a month. I was never told this and she told me that the government incentive isn't what he said it was. So I go back to calling XXXX XXXX again. Never getting through. Then they cancel our appointment to fix it and sent us a note saying to get a hold of generac for repairs!!. Then I heard they filled bankruptcy. So I stopped payments because I never ever signed up for all this and I can't afford any of this. My arbitrator from goodleap ( XXXX XXXX said the whole thing was messed up. I have every text from all of this. I think GoodLeap was trying to get everyone who was sent to them from XXXX XXXX to refinance and put the solar loan in the refinance!! Because they tried it with me until I backed out of it and then they were crazy and call me and tell me they were ready to go when I told the no I didn't want to refinance with them and not to call me back. Have proff on my phone of that too. PLEASE HELP ME. 
Thank you XXXX
