I have never experienced a more unprofessional company. I spoke with 4 different extremely rude supervisors trying to resolve why all the sudden after a year of paying off a balance there was a mysterious 100$ charge that I was told I needed to pay. While asking the supervisor to explain their polices to me he told me multiple times he was going to end the call and refused to explain their billing polices to me. They will absolutely try to scam you out of more money than you owe so keep every single record of all of your transactions with them. They are scam artists who have no accountability.
