Same. Ring and just hang up. When I tried to call back a recorded message said that the number was no longer in service.

Called me and said they were from some job seeker place, obviously an overseas caller of oriental accent, a crackly line too. I said that I was too busy to speak to them

They have rang numerous times, I answer with my first name only they hang up. I ring the number straight back, just hear background noise then it hangs up

Asked my name then hung up. Tried to call back but just music no answer at 07:40 ridiculous
