Summit Financial Corp Consumer Loan Complaint

Summit Financial Corp Consumer Loan department,

Vehicle loan Managing the loan or lease Georgia

My Auto loan is with Summit Financial Corporation in - Florida. My loan papers given to me from the dealership at the time of purchase state that my " payment due date is the - of each month, and considered late if paid ten days or more after the above stated due date and buyer will incur an additional $50.00 late fee. '' Summit Financial has not given me any New paperwork to sign for any new due date or additional fees, but began telling me ( after my first year and a half ) that i am past due. They are saying i am due on the - of each month and want me to pay micelllaneous charges but ca n't tell me what the itemized charges are. They do not send me a statement, but only a letter telling me i am past due, micellaneous charges of $300.00 dollars, no new balance ( balance never changes even after they get payments ). They argue that I have the wrong understanding about the contract and they they do not recognize what the dealership gave me. Only what is on thier computer screen. I have noticed that there are others on a blog site that are having the same problems as I. Surely they can not change my finance terms without me signing a new contract. Please advise.
