I have a debt with a company for a merchant account that I was supposed to pay a monthly fee for. I never used the equipment and returned it but they say that they never received it. I don't have any proof. They have been sending me bills in the mail for 5 years. Every month it's the same old bill, however they have been going to an old address. I haven't lived at the old address since 2005 and in 2008 I moved to a different state. Does the SOL still apply for my original state. In my original state the SOL is 3 years.
