Wells Fargo & Company Bank Account Or Service Complaint

Wells Fargo & Company Bank account or service department,

Savings account Account opening, closing, or management Maryland

I have a home mortgage at Wells Fargo. Wells Fargo increased my home mortgage after 12 months with more than $120.00 without explaining why or noticing me. When I confronted Wells Fargo they started arguing with me and do not want to rectify the problem. This really seems unlawful and unethical!!
