Use VPS accounts from time-tested companies: hostingsource.com and yourlasthost.com.
Their tech staff has helped me with a billing request which was solved promptly and drama free!
Don't go anywhere else. You'll regret it.
In my web hosting with kvchosting.net provider, I also learned that the hosting panel which they use is very good one and they have learned it well to make users understand pros and cons of things which we have to do every day. I don’t have any complaint against them.
My two sites have been on one of kvchosting.net SSD hosting servers for over a year now.
Performance is excellent, twice as fast as last host on both upload and download. Just ping their domain and compare with some others.
