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 ?
