Complaint Review: Spot loan

 I took a loan out through them like in January so on taking out the loan of 300.00 dollars I missed like three payments an when I talk to them they seem ok with an friendly so then I made up for cpl of payments so I ask for my balance for the three missed payments an it went from 285.00 too 400 after three payments so i was ok but then I made four payments of 49.00 which should bring me back down too 200 but then after that I said let me check my account it stated I owed almost 600 so after that they said if you need to miss a payment call them two days prior so I call them two days prior to my payment an they said That they couldn't stop the payment I called on Thursday an the payment was schedule for Monday they said it was a error in their system but to sum it up they caused my bank account to become negative so these's guys are a scam an I told my bank to stop payments cause they are a scam
