I get frequent calls from XXXX but when I answer they do n't respond. I did some XXXX research and learned that this number belongs to EOS CCA, a debt collection company that apparently buys uncollectable debt from various companies and then tries to collect on it. As far as I know, I do not have any unpaid debt and I have no adverse actions on my credit report, so I do n't know why they keep calling me. And since no one responds when I answer the phone, I ca n't even find out from them why they keep calling.
