3-4 times a day. All hang ups.

just called. No msg. Blocking this number.

Picked up ringing telephone, remained silent.  After a pause, the caller asked for my wife by name.  I didn't respond.  The caller hung up after about 30 seconds, but I had the satisfaction that they had to pay a toll charge for the call, and suffered some wasted time on the call.

Calls 4/5 times a day. Never leaves a message. Very annoying as they start at 9am

they asked to speak to a specific person... I said "what can I do for you" no answer and then they hung up
