Worse & worse

Like so many other reviews and reviewers, my recent experience with QVC and their selling partners, leaves a lot to be desired!
I ordered pies to come to Northern Ireland as I have done multiple times in the past. 4 weeks passed and no sign of my delivery. I checked their site and it stated these had been sent and delivered. I contacted QVC, who stated they'd get a replacement sent. No notification from QVC, however their website stated it had been posted. Again, I gave it 2-3 weeks, but no delivery. I contacted QVC, who told me that the company don't post to Northern Ireland!!
I advised them that I'd had at least half a dozen deliveries from this company. If they didn't deliver to Northern Ireland, how did the first delivery get posted, but not make it to me? Why did I receive 6+ deliveries in the past!?
I was offered £20 not to leave QVC when I told them I've had my fill with their recent inadequate responses and the cost of P&P and returns!! (Another online shopping service with a name the same as a South American river can post free of charge and return for little to nothing).
I'm now waiting for my last Flexi pay to clear, then I'm leaving with all my data with me!! I don't want to hear from them ever again as I've had too many metaphorical slaps in the face from this company!!
I'd suggest (given the reviews and average scores on this site) that QVC do a lot of soul searching and speak to their customers to try to change things around, as internet shopping is going to close them down....and their unique USP isn't going to save them!!
