Who called from 2816614151

Called work number and didn't leave a message.

Called, I answered, long pause then hung up like a bunch of fukin idiots

Repeatedly calls, but leaves no message.  Two calls in the last 90 minutes.

Called asking for Mr or Ms Such-N-Such. Told them to please remove my number as there is noe by that name that lives at this number. They just hung up without replying. Tried to call back and line was dead... it did not ring at all.

Called no message left, so I take they are spammers.   Tried to call back and dead line.
