Bitcoin Scammer. Grandefax scam.

Caller: Almost certainly GrandFX

This GrandFX mob (there is a legal GrandFex) are behind the endless swamping of multi-media ad-spots displayed online by GOOGLE ads (how to stop *them*?,) which feature photos of well known people. The ‘who is displayed’ almost certainly changes to suit the targeted country. I fell for the early d*ck Smith version, as their script writers are very, very clever, and got 'him' just right. (I know him from aviation). Burnt me to the tune €250. I woke up in time to back out & have written it off, but have been harangued since by their callers for 6 mnths now. iiNet & I set out to block these clever Cyprus and/or Russian based people, and emails vie iiNet are now prefixed with 'iiSpam'.

Now, anyone know how to block an inclusive >range< of *telephone numbers?

Number in same line from (08) 7100 1240 others ending in 41. 47,59,67,69 calling as late as 2220 on the 10thfeb 2020, I've already blocked several others

Showing up on Samsung mobile as potential fraud/spam. Also (08) 7100 1259. Ringing after hours!

Yes, disconnected number, yet another scam. Reject call & block

I called back number (08) 7100 1240 rang once then gets disconnected automatically.
