wants you to call   877-683-5490

Debt collection agency.  I called back, they DID answer, I didn't have to say anything but "Why are you calling me? and they told me which delinquent bill payer they're after.

keeps calling at odd hours and never leaves a message. We owe no money but I assume it's a debt collector calling a previous owner of our number. I've been receiving a whole slew of these calls over the past month from numbers in and around Boston.

frontier finanical/eoscca/eoscca!!  Medical debt scum on prescott st in worcester for this number.  All these companies are1 in the same out of nevada!  They will only listen to a court summons for them!

Eos is out of Massachusetts and does not seem to be connected to Frontier, who by the way does not have a charter in Nevada because it was revoked.  How are you equating both these debt collectors to be one and the same?
