I'm a sky tech support person, a customer has just called me up having had the exact same call type from this number.  don't give these scammers the time of day.

just been called on this number , she said it was to do with my payment protectin insurance claim. When  asked  why it was any of her business ,she hung up.

Had two calls within 5 minutes of each other. After reading the comments on here, I answered but  never spoke and they hung up. I'm exdirectory so how do they keep getting my number?

And me! Said they were from Talk Talk.

Just been called by this number about 20 minutes ago exactly the same as Andy. I reported this to Sky, apparently they tell you that you have loads of viruses and then try to sell you their virus protection.

Repeated calls within minutes woke me as I am a shift worker, very annoying. Tried to sell me something, I told them they had woken me, and how annoyed I was and they hung up.
