I would rather have been 100% sure. I didn't have the information I needed with me. And my mind drew a blank even though they told me stories referring to themselves as postman and his black and white cat. Thankfully I didn't phone. But when they said which one, there is two at that address? It threw me. And I realised when I got back to my car which one it was. But I got tied up with other business and decided that someone else would see to it.
