Got a call from this number today at 14:50, but didn't answer because i was busy, tried calling them back and it said 'sorry you missed our call, we'll try again later.' i don't have home insurance or anything, but it's frustrating because you want to answer these calls incase they are from banks, or insurance details, phone etc.
I agree with others don't answer, or if you do, don't give ANY details over the phone, I've always heard that if insurance companies or banks etc need any details from you, they will always write a letter especially if it's bank details! if you have given bank details just make sure you keep an eye on your statements.
