I had a call saying it was from Windows support. I told them I was so pleased to hear from them as the ones installed by Anglian were beginning to leak and I could do with some assistance. After a while of this, the caller managed to inform me that my Windows system, on my computer, was corrupt and needed fixing, urgently. I told him that, as I used an Apple computer, I was very concerned. He hung up.
When people call with the get rich schemes or wanting to sell me something, I tell them that I have just been made bankrupt. They don't stay on the line for long, then.
