When my loan payment was setup for autopay from my bank account there was a mistake on my part and I listed a checking account that I normally do n't use and my bank rejected the payment because there were no funds in the account that they tried to debit. When I received my loan statement for the following month I noticed the error and past due amount and made a branch payment for the past due amount. The lender had contacted the salesman that I purchased the car from to have him contact me to get a payment status. When the salesman contacted me I asked why they were contacting him and not me directly and I explicitly told the salesman that I did not want him communicating with the lender on my behalf that I would contact them directly. I called the lender the following day and the representative I talked to demanded to know why my payment was XXXX days past due. She threatened me that my loan was under review and they they were going to stop servicing my loan. She also informed me that they had contacted the dealership and all XXXX contacts that they made me list on my loan application regarding the past due balance on my loan. I informed her that the only person that I have authorized to discuss my loan with was myself and that they did not have authorization to contact the dealer or any contact on my loan application regarding my loan. She countered that they do in fact have the legal right to contact anyone they wanted to in regards to status of my loan.
