Go ahead and have an in-depth review of this website http://www.thehost-review.com I assure you it provides non stop 24/7 chat and voice support ......I found it rather impressive. All hosting companies promise 24/7 support and cheat you don't treat this as spam "BEWARE".....people who spam! Blame others. Go ahead and decide for yourself.
Going back to the topic not to the person. LOL, btw, if you're looking for free and reliable hosting then better check on this website. http://www.absolutely-free-hosting.com/best_hosts.php . However, if you have some sensitive info. and important data, I suggest you get a paid hosting plan.
I've been using free hosting sites for more than a year now but I've never really had that much traffic with it anyway the most reliable free hosting site I've tried is 110mb.com.
Even if some host would offer it for free, the service should be at least acceptable. But it usually isn't. All hosts have to pay for the servers, bandwidth and other expenses, so better you search a budget host, i can also recommend you Drupalvaluehosting.com.
