The only thing that could resolve server usage is putting you on a different server... Just having a more expensive account on the same server will do absolutely nothing regarding resource usage. I still suspect that some sort of malicious program has been hacked onto your server. That, or the hosting company put way too many accounts on one server, which is entirely their fault, not yours. If we can eliminate hacking as a problem, you definitely need to get in contact with the Better Business Bureau...
