Original Creditor XXXX XXXX - So they claim. 
Paid XXXX XXXX in XXXX 2009, before moving to XXXX, so how could I possibly owe them {$320.00}? 
Told XXXX XXXX to discontinue service, paid bill, and never heard anything more from them, even though left forwarding address with Post Office. If there were any additional costs incurred, certainly nowhere near {$320.00}. 
Never received anything from MEDCAH at all. 
Now they claim they want almost {$600.00}, including interest. This is nothing more than blackmail and extortion. 
These people probably bought this old utility bill from someone for pennies on the dollar, and now think they can ruin my credit, and demand {$600.00} for it. How can they be allowed to get away with this? This is a complete travesty of justice.
