rio resources aka mte financial services

i applied for a payday loan with ten dollar payday. this was a few months back. i received $200 from them. my first few payments were $20. no big deal. then they went up to $60. then i had some more financial trouble. now they are telling me i owe them almost $300 dollars and they are threatening to take me to check systems. they also tried to pull money out of my account 6 times within 2 days costing me over $150 in fees! i couldnt believe it. on top of the matter, now they are calling themselves mte financial. i closed my checking account. they are horrible. i have never had so much trouble with a payday loan company. never again will i do this over the internet. do you think i should ask them to refund the money for my fees from the bank?
