I've been receiving the same blank call from this number twice a day since May 2nd. We've tried complaining to the local exchange but they did not recognize the number as their own and asked to file a police complaint.

I've been receiving  blank calls  from this number since May first week.  no reply when we call back. its so disturbing.
