I had intended to reply yesterday afernoon but ended up much busier than expected.
You must be reading different posts to me if you think that's what the response is. The frusatration seems to be stemming directly from the fact that the message from OC is that DPD are to blame for delays for Irish customers when DPD are not responsible for delivering the cards to Ireland. That is OC's responsibility and I think there is a stark contrast between what you wrote and later claimed is "essentialy what has been said" by OC and what actually has been said in this thread. To your point elsewhere that being annoyed will not do any good, you're not wrong but try that arguement on your partner next time they are upset and see how it goes.
There have been a wide range of responses, and the number demanding the impossible is higher than it needs to be.
For the DPD issue, as I understand it (from feedback received at least) the issue is DPD gave criteria for Irish delivery processes to OCUK. OCUK (and other businesses, I imagine) had to go like hell to meet the criteria for these, because there were about 3 days between a brexit deal being agreed, and needing to be implemented. However, once this was done (or during, I have no idea), the goalposts have been changed and the process started again. It may be OCUK's responsibility to deliver the products purchased, and they have chosen a courier to do it who on this occasion, appear to have let them down massively. They're in a position where they can't get in what they need, and can't get out what they have, and in both instances it's due to factors outside of their control.
I don't think there is a stark contrast. I said "Oh sorry, actually we've been re-keying every item we stock and sell due to a number of forces outside our control for a bit of a giggle, we'll get them all out in a bit." Sure, I was being a bit flippant as previously noted, but apart from the giggle, that IS essentially what is happening. ScottiB explained that they need to rewrite a hell of a lot of information in order to be able to sell. He's gone in detail a few times about what needs to happen, but it pretty much boils down to far too much to do in too little time, with uncertain criteria to meet. Can't be too many businesses where once you finish, you decided to go onto a public forum on your own time where people are slating your work, you try to explain things and get some pretty unreasonable replies. Not all, granted, but there have been a number of feet stampers.
As for pointing out to my partner when she's annoyed? She's a rational person, and I love her greatly for it. If she's annoyed, it's probably because I did something that was a) Within my control, and B) Pretty stupid/thoughtless, therefore she has recourse to seek an apology.
Trust me, that happens.
