Who called from 5015100410

This number has called my cell several times. They do not speak to me. When i try to call back the number is 'out of service'. Just very annoying. Wish my cell could block certain numbers.

Same thing happening to me.  Calls me around the same time every evening for a week now.

How do i block these pricks from calling

Scammers, I blocked this number.

Calls like the above and you can not call back or not in service......I put the in my contact as SCUM  and when they call again I know to ignore them.  Currently I have 30 scums in my contact  so when someone calls and it say scum and not a number I have to laugh, no guess work and I do not try to call them back.  LOL
