Couldn't say what kind of company it is, they've called twice in the last 24 hrs and haven't left a message. Since I won't answer numbers I don't know I guess I'll never know who they are except annoying. Legitimate debt collector companies really find better luck in sending me a letter with all relavent information including the origination of the supposed debt, but at least I'll contact them.
Made multiple calls to my cell (which is also on the DNC list ), & leaves no message. I also NEVER answer calls I don't recognize.
I feel that if they don't leave a message, they don't require a return call.
(Probably scammers!!!)
