I've also noticed this.
I have sent one email regarding something that was worrying me greatly, and still is.
It's regarding blatant multi-clicks on ISPCheck (viewable even by the inbuilt ISPcheck stats). I sent that on the 7th of this month.
I also have never been notified of my campaigns starting (I used to), nor the stats of said campaigns (banner ads).
If someone wants to get back to me, contact me @ s.orourke[@]eirca.net
I'm a little dismayed that Christine is VERY quick in replying, but no-one else seems to ever reply.
It's annoying me, because for a month we kept ourselves on top of the resellers list, but have now withdrawn from making further advancements, until our issue(s) are cleared.
