I ordered something online that was being delivered. The time frame they provided was between 8.30-6pm and I waited in all day apart from the school run and they tried to deliver it then. It got rescheduled to the next day and they assured me it would be the morning. Again they attempted delivery when I was on the school run. I ended up phoning and saying this is going to keep happening so can they just leave it behind my gate in my back garden if they come during the school run. It was a high value item so it was meant to be signed for but they agreed to this. They again came during school run today and said they'd left my parcel in a safe place except it isn't there. I phoned up and they said it was left in the agreed safe place and I consented to that and am liable for the item from that point onwards. It's a high value item in a box that obviously states what it is so I feel like the drivers seen an opportunity and kept it and it seems there's nothing I can do about it?
