they call and leave a message to call.  they are a collection agency or something.  the person they were looking for doesn't live here and i have called them several times to take my # off their list!!!  so far they haven't :(

You need to send them a "not me" letter by certified, return receipt US mail.  Without further information, I can't help you especially since you don't remember the name of the company.
Read up on your rights here, get template letters to send and also make a complaint at this government site:  http://www.consumerfinance.gov/
Also file a complaint with your State Attorney General's office.
