John Moore Plumbing review: Spam me out of money

John Moore plumbing service spam us out of our money, We was charged $8500.00 for plumbing to be fixed. The next 2 days after John Moore finish the work the plumbing start back doing the same thing it was doing before the John Moore servicemen came out. I called to compliant about the plumbing problem being the same as before, and they came back out and said they found something else that was wrong with the plumbing. I needed to pay $21.000 more to get my plumbing fixed. I ask why would they take $8500.00 from me if that service they did was not going to fix my plumbing. I would not have spend $8500.00 on plumbing service that was not needed at first. They took advantage of me. I am a disable Veteran, I can't pay $21.000 more for plumbing work. Now I am stuck with the back up sewage coming in my home. I have to run a power jet in my sewage pipe or run a snake line down my pipes to get the sewage to clear. I am doing the same thing for my plumbing problem that I did before John Moore came. I paid $8500.00 to John Moore for nothing. I was taken! I am really hurt over this. I called John Moore and they now say to me that they can't do anything for me, I need to pay to get my plumbing fixed. I thought that was what I paid for at first. Can any body tell me what I can do about this please.
