Bob's Discount Furniture review: Over charging senior citizens

We leased $900 worth of furniture from Bob's in Rockford, IL so far we have paid $700 of it. We called to find out how many remaining payments we had, as we are on social security. We were told we have a total of 14 months worth of payments, which comes out to over $2, 500. We complained, and were told to read out contract. Well, we have no contract, and we are leasing, not financing. We would gladly return the furniture, but were told we could not get any of our $700 which we have paid in returned. We are on a fixed income, and they are taking advantage of Senior Citizens by charging them double what the price should be. Now we do not know what to do. We can not afford to pay $2500 nor can we take a loss of $700 with nothing to show for it. This in our minds are criminal, for taking advantage of us.
