I have been getting these calls every 3-4 weeks for the past 6 or so months. I've never answered them, much less returned them. I know I don't owe any money to anyone, so I'm not worried. It's just really annoying. Since they don't identify me or themselves or who they are calling for, I've always assumed they are scammers. I only found who they were by doing a Google search on the call-back number they left. The number usually shows up as 720-526-3002 on my called id, but they always leave the 888-407-5650 number that leads to Westhill Exchange LLC.
Caller: Westhill Exchange LLC
Call type: Debt collector
