Incorrect address on my contract and profile

I went through the online application process to rent a solar system with GoSolr with a sales rep on a telephone call (who refused to do a site visit), only to find that he entered a completely incorrect address on my profile (wrong street AND wrong area; when I checked on Google maps this incorrect address exists). When I told him it's wrong, he wanted me to keep it there and wouldn't change it. I changed it on my side, but by end of application the incorrect address was on again. When I asked him to change it he promptly started a SECOND application on my profile. So now I have TWO contract submissions on my name for two addresses and he wouldn't help me to delete it. They have a copy of my ID, permission to debit order and 3mnths bank statement. I'm terrified they debit order my account and someone else gets my solar system.
