The caller ID for this number shows up as DONOR SERVICE. They usually always call our business line between 4-7pm, including weekends, though twice they called around 11am. I finally gave up and called them back. They are the Donor Services Group, calling on behalf of the L.A. Gay and Lesbian Center. However, they also call for other non-profit organizations, too, using other phone numbers. It is a fundraising call. Our company has a business relationship with LAGLC, and one of the company owners regularly donates to this organization -- which is why I'm sure, we're receiving the calls. However, they never leave a message, and they call DAILY. It's rather annoying.
