Called by this number multiple times today. The call drops out / fails with each call. Very annoying.

Answered first call, was an ?energy company. Said no thanks, he said no worries. Have since had 5 calls from same number over 7 hours. Try to call them back and get a “call failed” right away. Just answered another one, no one on the line and it disconnected on their end

This number has called me at lest 6 times today on both mobile and landline. No message left, finally called back and got nothing just beeps. Answered 1 call and again just beeps.

5 calls in the last hour, never answered, who are these people ?

Keeps calling. No message - number just looks ‘wrong’

This number keeps calling, stays mute when answered then hangs up within 10 seconds.
If I call this number back, it’s considered invalid
