I don't need Instant Messaging with my host.
Writing an email, explaining my problem : 5-10 minutes
Initiating an IM session, explaining the problem, waiting for feedback (in case they/he are/is busy), talking more : easily 30 minutes
As long as there is a reply within an acceptable timeframe, I don't give much for IM support options.
Also, judging from the aforementioned lack of professionalism, I wouldn't expect them/him to be able to help me very much...
I may be wrong, but that's the impression I get from the website.
