Scam/Fraud
16 Sep 2025

Said from Sky. I live in France but still have UK number. I told caller 5 times that I'm not allowed to buy Sky. He was trying to get me to open up an email and give them a code on the email to get a discount. Yeh, good luck with that. They had my email address, obviously phone number and said that they could see that I had TV, internet and landline through Sky, (I did but not for over 8 years). Have Sky had a data breach?
