Scam calls

[HollyB6616]

I have been receiving calls from mobile numbers on my landline, when you pick up they hang up. Three times this has happened & when you phone back they have no idea who you are nor do they have anything on their phone that says they have rung that number. 
yesterday I had some phone on the house phone saying they were from sky broadband, telling me my internet was running slow & asked my to do a speed check on my phone. He also asked me to use another device to do this with, he was very angry that I didn't have an iPad or tablet to do this on. He said that he'd booked an engineer. He asked me no security questions whatsoever.

@HollyB6616 these calls are a pain but see this pinned thread.

Hardly surprising, given that's 100% a scam caller.  ISPs never call customers about slow internet connection.

@HollyB6616 Us too - we have ended up removing our landline phone as they tend to ring that number rather than mobile
