I live on the 13th floor in a block of flats which I appreciate is a bit time consuming to deliver to. I think Royal Mail have a key to get in with, not sure about Parcel Force. The whole blocks just had extensive work done and the intercom system has been re-vamped and is loud! It definitely works and I would have heard if they called. There have been people outside working all day too - it is usually no problem to get in the building. I've also been watching out for the van all day as i'm very eager to get my parcel. The van usually parks right outside the building but I haven't seen it today.
I suspect they didn't have time to deliver and returned it to the depot. I can't see why they wouldn't leave a card otherwise? This is quite naughty of them as the delivery was guaranteed for today. If they didn't attempt the delivery then they have breached the terms of the contract. So by logging in the system that the delivery was attempted, when it wasn't, they have covered their backs.
The main problem for me here is that I have no way of contacting them, apart from emailing customer services which is a slow process. There is a chance the item will get returned to sender before they email exchange is finished and I will be charged for re-delivery. And if they don't leave a card when they come I have no way of knowing where my parcel is or how I should retrieve it. I cant even take my card along to the post office to ask them.
Hopefully the Redelivery Schedule is for tomorrow. I guess I will have to wait in for 12 hours, from 07:00 to 19:00 to see if they come. If they fail to deliver and don't leave a card tomorrow I'm not sure what I should do? Will cross that bridge when I come to it I guess.
