Caller (with a heavy accent, hard to understand) said he was calling from the Do Not Call Register (rather ironic!) and said we paid our bill by direct debit and our credit card was due to expire this year and could I confirm the expiry date of our card when Isaid that was not true. .I gave him the date and then he asked about the bank, at which point I hung up after saying I was not discussing any banking details over the phone on an unsolicited call. Weird call!
