Power Home Remodeling review: Horrible company

Signed up for window replacement, no problem, price reasonable, not bad interest rate. Day of install another salesman showed up to sell me a new roof which I needed. Told him I could not afford until I paid off the windows. He asked if he could get the payment the same would I do it. I said no the only way to do that would be to make the loan longer and I did not want to do it. He came back and "I got you a better interest rate and we can do the work for the same monthly payment." I signed (my bad) not realizing he had MAXED out my credit by adding many things I did not need (gutters, vents etc...), then ADDED 10 YEARS to the contract, which he conveniently covered with his hands while I was signing. I will now be paying for this well into my retirement and cannot do other needed repairs. If I had stuck to my original contract would be paid off next year, I kick myself every day for dealing with this company.
