I don't know if it's happening in Britain, but today in Denmark I've already had three calls from these lowlifes.
The first time I just told them to f... off. The second I told her I was going to switch my computer on and put the phone down for 15 minutes before she hung up.
The third time I was royally pissed and told the toe rag that he would go to hell with all the other scum. Amazingly after that tirade he STILL tried to convince me he was genuine!!
Anyway this is just a heads up, in case they pulling the same scam in Britain. Please warn anyone who's vulnerable to these conmen.
