Hacked!

On Sunday I had the fraud department of Barclaycard on the phone asking if I’d spent £500 in a hotel, £90 in Pizza Hut (as if I would even go there) and £50 on delivero! Obviously it wasn’t me......so hopefully they will have refunded the amounts. This is the second time in a few years that this card has been done and as it’s only ever used for internet purchases I am coming to the conclusion that either I stop buying or find a safer way. Any ideas.....I use amazon but they don’t accept PayPal....perhaps cash is the only answer but there are things that I get that are not available within 100 miles of home. Help....
