Who called from 7788065092

Multiple calls daily.  Very annoying, take up space on my messaging service.  Can you make them stop?

Caller's name  not displayed on my phone. In such a case I do not pick-up he receiver. Did google for the number and ended-up with this form to tell my story.

Rude...asking for donations. Calls multiples times daily.

Half dozen calls a day, no response when I answer. Tried calling back and got a recording. How do I block it?

Same as others. Annoying calls many times a day. I do not answer if name not displayed. Thery never leave a message. I answered once months ago. No response at other end.How do I block these calls.
