US fast Cash Online loan Scam Internet

I received a $300.00 loan from them, and they were suppose to collect repayment via electronic deductions from my checking acct., they never clearly communicated that i would have to initiate a lump sum sum pay off to avoid ongoing interest charges of $90.00 a month, i thought the $90.00 deductions were payments toward the loan, until it got to the point that i had paid them $360.00 on a $300.00 loan!  I called them to find out why they were charging me so much, and they said it was in the
fine print basically and for service charge. I said what service? You didn't do anything for service!  I think this company is very sneaky & sly, they purposely hide important information from the consumer so that they can rip people off and claim no fault in the matter!  I intend to put a stop payment on any further charges from them, as they have more than received their money back!  I would highly discourage anyone from using this company, no matter what, because they are total scam artists, and
they should be shut down!
