I keep getting numerous calls from this number, nearly once per day for the past month. Like others on here, they never leave a message and when answered I hear the word "Goodbye" before I am able to say anything. I can't block the call because the NNX (the 059 part of the number) is not valid and the call block service will not accept it. This sounds like some kind of prank call or a scammer who doesn't know what they are doing. Either way it is getting very bothersome. I plan to file a complaint with the Feds.
