I've gotten 6 or 8 calls from this number in the past week. Twice they left a partial VM that starts at the same spot "...for the inconvenience" The callback number they leave is different ... 661-670-2619
I called them back, and asked them to please take my number off their list, as I don't donate over the phone. They were very apologetic, and the person I talked to assured me I wouldn't be getting any more calls.
I was stupid enough to donate to the HRC for two years, even though they ignore low income gay and lesbians and treat transgender people like [***]. After I stopped donating (because I am unemployed and because of what I discovered about them) I started getting robocalls from this number soliciting donations. I've told them to stop and they still call. Really annoying, and between this and the amount of spam mail I get in the physical mailbox from non-profits I'm seriously considering never donating to anything again.
