they call, you pick up the phone and the connection is cut.
You call back the number - and always the same spooky voice says that all operators are busy and the will call back - what never happened

same here 19/10/2018 1130am

I called back the number - and it says that all operators are busy and the will call back. I have blocked the caller

this number is been calling me since 2 days and no one speaks when tried from landline to ring them it states all operators are busy WTF.....

They call repeatedly. If you call them back, they say all their operators are busy, but they don't identify themselves.

They called yesterday and today and I missed both calls. I called back and got the message bank says that all operators are busy and they will call back. Doesn't say who they are.

When you answer the call hangs up - when you call back - just a message saying they are bz

rang but no one on the line
