Just answered the landline (no caller ID) and a 'foreign' gentleman announced himself from being from my PC internet connection department, and proceeded to tell me that, from their records, each time I connect to the internet it is showing as a slow insecure connection.
I asked him what company he was calling from and he rattled off 'sky, virgin media and talk talk' - I said 'that's very strange 'cos I'm not with any of these companies' - boy did he put the phone down quickly!!!!!
