Thanks Huggers. I rang the driver this morning when we found the sorry you weren't in card with his number on and he says he definitely delivered them and tried our bell twice but I'm sure we would have heard it. I just got off the phone from the company we ordered them from and luckily they are sending us a replacement so that's good. I'm just a bit peeved off because we've lived here less than a year and had this theft, a few bags of cement and sand stolen from our back garden last year and an attempted burglary (he was caught and charged though) so we're feeling slightly unlucky today and I know they're only thefts so not the end of the world. These things come in threes supposedly so hopefully that's the last theft we'll have!
