pick delivery date bs

I wanted to order a shed and get it on its way but knew I was going away for a few days so I phoned to check on average delivery times and was told I could pick my own personal delivery date. Super I thought I can arrange it and not mis the driver.
ordered and paid for it but was never given the option of delivery date. then got a email from yardmaster the shed supplier with a telephone number so I phoned it to schedule delivery and they said it depends when driver was in the area. so I told them the dates I was away and guess what!!!! yes you got it the driver rang me wanting to deliver it the day I was away.. Driver Said no details of my dates passed on to him. he even stated they never pass them on. I suspect it will stay on his van for next few days getting kicked around now until I am back and able to take delivery. ill keep you posted
