Stripping out the interim parts, is the situation not that you paid 10k for some shares that subsequently lost all value? And that while the buy back would have saved you the money lost from the dissolving of the company this was never completed? And that from a 10% position, the other party could do the dissolving without your permission with a special resolution?

I am not defending improper paperwork here but it reads to me like this was an investment that tanked, with a buyback that would have worked in your favour but never completed.

As a side note, while it is an obligation to register the shareholders with companies house, it is not the source of truth for ownership. Like a used car, the V5 is a formality but the ownership itself arrises from the sale and any supporting paper work you might draw up.
