As usual, Siteground's Customer care is perfect, helpful, and up to the point. The agent performed in an empathic and helpful way. Shame is that now it is so difficult to reach an agent. And the IA in the chat is slow, and usually does not even read my question, so, it answers something else. I've asked how to download a backup of my site, and only at the very beginning it said that this was a Premium feature... must have said "this is a paying feature, not included in our standard services"
