When I purchased my home in 2006 I believe that I had obtained a rate whose rate was only fixed for 5 years and would adjust afterwards. When the 5 year mark arrived the rate did n't adjust. I contacted Wells Fargo and they insisted the loan was with a fixed rate and the rate would not be changed. I tried to refinance the mortgage and despite many attempts they have refused to refinance my mortgage under any circumstances. 
I reached out for assistance from Wells Fargo and despite the fact that I sent the same information repeatedly they insisted I had not furnished them all the information required. They also kept moving my case to other people. It seemed that they on purpose would request the same information over and over just to discourage you from asking for assistance. 
I have been current with my payments and I am locked in a mortgage at close 7 % which is far higher than the market and ca n't get the bank to refinance me. I think the mortgage when I first signed for it was misrepresented to me and I believe that in order to correct that misrepresentation some accommodation should be reached.
