I hate having parcels delivered by RM - our regular postie is lovely but I have never received a parcel to my door, I always receive a "Sorry we missed you" card.
Which would be fine if it wasn't for the fact that the sorting office is only open 12-2 and they want you to wait 24hrs after you get the card to go and collect even if the postie didn't actually bring the parcel at all.
I had a parcel due for delivery last week (had a safe place designated on the delivery, as always) and was literally standing in the hall next to the door putting my coat on to go out when the post came through the letter box with the red card on top. The postie had the decency to look sheepish when I immediately opened the door and he admitted he didn't have the parcel with him and had left it at the sorting office, hence the card and no knock.
Since it was my day off, the parcel hadn't actually left the sorting office and I was at work the following two days when the sorting office was open I went straight there with the card. I was then told by the member of staff at the counter very dismissively that I couldn't have my parcel as "It isn't here because we have to wait for the postie to bring it back from their round, did you not read the instructions on the card?".
When I told her the postie hadn't taken it on his round in the first place and had our conversation on video (ring doorbell) to prove it, so I knew it was there, she tried to argue that "regardless, the card says you have to wait 24hrs so come back tomorrow" until I asked for her supervisor to make a complaint about the service I'd received (or lack thereof) at which point she reluctantly went off to find it and came back with my parcel a couple of minutes later.
I have no issues with the posties wanting to reduce the pressure on their rounds by not carrying parcels but you can't offer a parcel delivery service, routinely not deliver the parcels and then have staff being rude to customers when they are trying to collect them. I am more than happy to collect my parcel from the sorting office, providing I can do so on the day it is due for delivery and in a reasonable time scale (ie not just open 2/3hrs in the middle of the day and without having to wait 24hrs even when you know the parcel never left the building).
