rude people, they wont send me a copy of what I supposedly owe them lol they said they'll accept credit card payment today over the phone. They wouldn't even explain what I actually owe on the phone either but expect me to pay over 20k owing + late fees hahah told them I'll pay nothing at all and to take me to court and hung up. update.. keep receiving text and calls, they still wont tell me what I owe money for.
