I regularly get messages from O2 UK saying (below a tel. number) "this is a free call alert from O2. To disable this dial 901, press * then option 4 and option 5"
Forgive my ignorance, but is it all about? I once followed the instruction and a voice message was saying something like "you need to change your pin number or you'll be cut off withing a few days". Obviously, I have not acted on any of the above, but am getting fed up of receiving the same message with a different phone above it. Any help would be most grateful, as I am extremely suspicious of anything asking me to change passwords/pin numbers etc. Is it a scam?
