mikyilfilosofo If you know how to solve the mystery of the cloned site, I would thank you
It seems none of the actual team worked in this way on your website clone, also it is very likely happened more than year ago when Joomlabamboo was not yet acquired by joomlart so the support team at that time was made up of other people.

I'm at joomlart from many years and never and again never i have seen something like this, this is not our normal way of work, i'm not offended by your question but i want to make clear this is not our normal way of helping users.
In any case i don't think would be a problem for you now to delete the cloned site definitively. And please accept most sincere apologizes ( And we do it not on our behalf ) if this situation caused any type of issue to your business.
Best regards.
