Exeter Finance LLC review: Financial services

On 8-7-2022 we started getting notices that we owe a exter $487.62 on top of the $700 payment we've made every month since we've had the vehicle and can prove with bank statements and confirmation numbers it started a few months ago and the first rep I talked to said it was because of a new system and not to worry about it. Other reps wont tell me why I owe just that I owe but they said its $432 the supervisor even hung up on me very unprofessional company and very suspicious work ethics. They need to be investigated for scams
