Worst ISP ever

The very worst company that i've ever dealt with. It's been painful to try and phone them as NO ONE answers. It's almost like they operate on skeleton staff the entire time. info@accelerit is merely a mask as they don't seem to be reading their mail at all, just like their phone calls.

Now, my account has been suspended after sending through the proof of payments done three weeks ago and, when they eventually answered, getting to acknowledge that they have received the proof of payment. I HAVE EVEN LOGGED SUPPORT TICKETS TO GET THEM TO RECTIFY THIS ON THEIR SIDE.

What more do they need? Do we need to actually go there and do all of our own admin on their system as well?
