Arvixe Internet company removes services to upsell Internet

I signed up for a plan that was supposed to fully run Boonex Dolphin which was on a shared server.  This involved running a server called "Ray Media Server" without which the Dolphin product's chat would not operate.  I had planned to make the chat central to getting people to come to the website, but when they did what they called an "emergency rehost" in September that had my site down for a week, the media server did not work.  When I reported it, I am being told that they do not support it on my class of service and I would have to convert to a more expensive service to use it.  This is "bait and switch".  This company has had other times where their maintenance would suddenly make my web site go down for days.
