Fast Bucks in colorado

i have a question. I recently wen on a payment plan with FastBucks here in Colorado. I had been paying my loan every 2 weeks, even though i am paid weekly. When i went to get set up on this loan they now said i have to go in and pay my loan weekly. I dont think this is right. I went in and the manager that told me that wasnt there and the employees set me up on every other week and I got a nasty call and was told that i have to come in every 2 weeks. even though my check is dated 2 weeks out. does any one have an answer or know where i can find the answer to my situation?

Thanks

k
