My home mortgage documents/regulation z which were originated on XXXX XXXX, XXXX states that my monthly payment would be {$5100.00} beginning XXXX/XXXX/XXXX. I received a letter from Wells Fargo stating my new payment is {$6400.00}. When I called Wells Fargo, the customer service reps have no answer for the discrepancy but say I must pay the {$6400.00} or fall into foreclosure. My interest rate is locked at XXXX % currently and all other previous annual increases have been in accordance to my signed loan documents. I feel this is totally unfair, unethical and a breach of contract and would like immediate help in resolving this matter.
