No message left every time blocked the number

I have had many calls from this number in the last few days. They are nasty and rude and should be reported but I would expect the number is spoofed.

This number has called multiple times in the last 4 hours and they are abusive. I was asked if I liked to lick my anus and that is only some of the things said before I hung up. It is a call centre of some sort and I have had the calls on both work and home phone numbers. If they continue I will make a complaint about them to the Police and the Department of Communications.
