Wells Fargo Bank is not applying extra paid on the payment to the principal they apply it to the next months payment. I called them to complain and at first I was told they do not apply the extra to principal they did not have to, and there was not way for them to do that. They do not give an option online when making payments for extra to be given or applied to principal. When I stated that is not legal then they tell the only way was to send in a check by mail with instructions to apply to principal otherwise it would be credited towards the payment/interest.
