Wordclay speak to me from the grave

Not from this grave!  - this is Mum's

Last week, having found out that the publishing companies: AuthorHouse, Vesta Publishing, Lightning Source and the now defunct Wordclay, were all part of the Author Solutions empire, I used their online form to communicate the following message:

Re: ASIN: 1604818743 The Glassblower's Daughter 
Dear Author Solutions,Can you confirm you are the publisher of the above item which is one of two titles that I published with Wordclay? I am having difficulty understanding how Wordclay went out of the business without telling me who I now need to deal with to get information about how my titles are selling. Amazon have investigated the mystery and they tell me that AuthorHouse publish my title. But when I rang AuthorHouse yesterday, they denied any knowledge of either of my titles.

I did not get any reply that day or the next and was also busy trying to talk to Amazon and the other players listed above (see previous post).

But today Hurrah! I got a message from Wordclay. The message above had been forwarded to them perhaps ( I am guessing) and they said: to paraphrase:

Greetings Frances,
We were your publisher but we have closed for business now so now you have no publisher. We have asked all resellers to cancel your titles but it might take a while so your books might still be available for a short while. Final accounts will be settled before April. 
Best wishes
Wordclay

Phew - what a relief. So if I want to carry on having a paperback version of my books I will need to sort out some other arrangement. I wonder why Wordclay couldn't have sent a message like that when they made their announcement about closing down, back on December 4th.
But there remains an unanswered question which is this: how come Vesta Publishing and AuthorHouse are listed on Amazon.co.uk and on BooksEtc as being the publisher of my titles when they are not?
Amazon.com, I should make clear, has continued to list Wordclay as the publisher.
I assume that the answer is really simple. But if it is, why don't the companies listed know what it is? They don't even seem to talk to each other let alone to me.
