Who called from 9512629064

called 3 times 2 hours. No message left

Repeated calls.  Does not answer, just hangs up.

Repeatedly calls. Leaves no message and when I answer no one responds.

Called and I delcined the call, which automatically blocks it.

Calls me 6-8 times in a day.  When I answer it hangs up.  I called back and no answer.  It gives me the option if I think the call is a mistake to press one to be taken off the call list.  Hopefully this will take care of the problem.
