illegal business model

All spam calls I receive from local (swiss) numbers can be traced back to this horrible company using the offical number block lookup tool by egov.swiss

Had a call this morning from 07451 235644 which is hosted by this Dutch company. It was a phishing exercise alleging unauthorised credit card use. It seems the same outfit uses many numbers with the same 6 initial numbers for similar purposes. Since this seems bleeding obvious where arent the telecomms authorities dealing with this ?

Its a scam call ..

Its a scam call ... get it 'it tis me'
How ridiculous can the scum of the earth get? I dont blame the scammers, I blame O2 for delivering the call. If the sevice providers would get their act together and block these calls the world would be a lot safer.
