NBCC National Bureau Collection Corp Fraud; Inaccurate amount due; Unknown company Internet

This company first sent me a bill for nonpayment to BodyBody.  It was for an amount way over what the bill was.  The charge came on my statement as Swimsuits Online.  They tried to rip me off as well.  Once I threatened to bring charges and that I was canceling their payment, they finally sent me what I ordered.  They never responded to any calls or emails until that one.  I reversed the cancellation as soon as I received the last item.  Then I received a letter from NBCC saying I owed $200 more than the original amount.  I sent proof of payment to both BodyBody and to NBCC.  I have heard nothing back about that.  I just today received another bill from NBCC for a company called Ranowear, Inc.  Never heard of it.  NBCC does not have an email address and no person answers the phone.  You can only leave messages or pay the bill.  I have left two messages informing them that if this shows up on my credit report or if I receive another letter, our next contact will be through a lawyer.  We will see how this goes from hear
