Scam caller. Couldn't confirm my details. Tried to email me with code to take over my account. I'd given a fake email address and they kept asking for Auth code. I asked them to confirm my address where they had said they would send a SIM card to. They couldn't confirm anything. Managed to waste 11 minutes of their time before they hung up. Amazingly they called back whilst typing this and I managed to waste another 6 minutes of their time by acting like a moron. Hoping they call back again. I was telling them about my grandmother being very old.
