There were so many conflicting statements made, they couldn't all have been reasonably, probably true.
1) Statement posted on QVC stating TRPC were taking a break and that there were definitely no quality issues.
2) Statement on TRPC website stating that they are in the kitchen "whipping up some fantastic new pies."
3) Statement on TRPC's voicemail saying that they were closed due to "a supply issue."
4) Statement on TRPC website from Lee saying that they they had been hard at work buying out shareholders so that they could bring the quality back.
So what to make of the above premises? Well, they couldn't have been "on holiday" if they were "in the kitchen whipping up ...new pies," and they couldn't have been "in the kitchen whipping up ...new pies" if they had a "supply issue." The flat-out denial of any quality issues by QVC indicates that there like WERE quality issues, and this is back up by Lee's statement. He comes across as a more honest, if not foot-in-mouth gaffe type.
Given that no small businesses would likely wish to take such a long time off (they haven't before, to the best of my knowledge) it is most reasonable to conclude that there were some internal wranglings at TRPC, and that they tried to get financial backing by external shareholders but were not happy with the changes to the products that were likely forced on them, therefore they had to secure funding to buy them out. Maybe the y had got in the shareholders because the company was struggling financially, or maybe they were simply trying to expand. We will never know because TRPC is excluded from having its accounts audited by Companies House. When their turning increases to > £1,000,000 however this will change.
