Wells Fargo & Company Mortgage Complaint

Wells Fargo & Company Mortgage department,

Conventional adjustable mortgage (ARM) Credit decision / Underwriting Florida

My credit bureau report shows me being late with my primary Wells Fargo loan and a second lon as - being late./ This is an error. I was late as indicated in my file for the second loan but the first mortgage loans was always on time and was not late. How do I have this changed? I 've written to the bureaus on-line but have never received a response back.
