Such thing as an unsealed AGM battery??

After speaking to the RAA's supplier for deep cycle batteries: Club Assist, they assured me that their deep cycle batteries were AGM type despite the RAA telling me that their deep cycle batteries were not AGM but calcium.
The local RAA supplier checked with Club Assist who told them that they were AGM and with a single valve.
I went ahead and ordered.
Batteries arrived and they were not sealed and immediatly started to leak from the 2 top multi plug stoppers. The local supplier removed the plugs and the batteries were full to the brim with liquid acid. I didnt look closely for glass matt.
The local supplier, without actually checking the batteries for mat and apparently without knowing much about deep cycle batteries, insists that they are AGM's and was quite abusive when I told him that clearly they are not sealed and therefore not what was described both to him and to me: no point having a valve on an unsealed battery I would have thought. Which makes me think that Club Assist were describing a different battery to the one that the RAA sent.

I am guessing that the RAA sent a calcium deep cycle being unsealed (which is what their technical dept thought they supplied) but my question is, are there such things as unsealed AGM's?
