Had several phones calls recently stating I have problems with my windows and that they work for Microsoft. I could hardly understand as they had a very heavy accent. They rang again today asking me to switch on my computer they normally ring off when I say I am using an IPad. Anyway I said do you really work for Microsoft they said yes, I asked where they are based no answer, I said I know this is a scam, guess what, they told me to F.O. Pam my wife was quite shocked as the phone was on speaker. I assume nothing can be done to stop this.
