I have just been hit by an aggressive collection agency for a $191.00 utility bill from 2002 (last activity). I am trying to figure out the SOL for utility bills in Missouri (although I now live in Oregon). What I need to know is if this is considered a written or open contract? The truth is, I don't even remember this account so I am so confused! Either way, if it is an open account I am sure the statute of limitations would prevent further collection. Thank you for your time.
