Yep, same here. Virtually given up on RM except for basic unimportant/non urgent letters. Sending all our parcels, small packets, etc via Evri now.
Also buying as much as I can from Amazon rather than ebay or retailers' own websites so that I know it'll be Amazon delivering rather than Royal Mail.
I only had two RM parcels due to arrive here this week - RM managed to deliver both (different days) to the wrong address (different addresses), and I was in both times as it's an office, so I'm here 9-5 with a "shop front" office, so not only can I see people walking past, I have a direct view of my office door, so know for a fact that the postman didn't come to my door on either occasion to knock/ring the bell, and no card was left either.
They just seem to randomly abandon parcels/packets where they feel like it. I checked the tracking on both, and both were supposed to be tracked 48 with signature, but on both cases, the signature was the same, i.e. the postman himself, not the recipient, so paying for a signature is a waste of money!
I have no problems with Evri (sending nor receiving) and no problems with Amazon (receiving) either.
RM have completely lost the plot.
