I found plenty of reports online regarding bad services in 2007, 2008 and even a posting on RipOffReports (which is it's own discussion I will not get into here).
What I did find however was the cancellation procedure for webserve.ca -
http://www.webserve.ca/support/cancel/
I also found their Legal page, which covers terms of service -
http://www.webserve.ca/legal/
I also found that they state they offer a 30 day refund, except for setup fees, but if you are outside of the 30 day refund timeframe, then section 1.2 comes into play which states that they will not refund if you terminate within the initial term. If it's after the initial term, then they pro-rate refunds.
Since this is an issue regarding a refund for services, and not an issue of someone "pretending to offer services", I would continue with your legal resources, contact the authorities and request a refund on your credit card or payment method that you used.
I strongly advise you to refrain from saying that someone is pretending to offer a service, as there is no actual pretending. While they may not have delivered a product on time, and then a refund reqeusted and not delivered, this is not the same as saying that someone says they offer something and in fact do not. If you continue to issue such statements, you might quickly find yourself in court for defamation through libel statements.
With regards to your future in choosing web hosting companies, please be sure to check google and various other sources regarding a hosting company prior to starting services with them. The basic search of just "webserve.ca tos" yielded 5 results in the top 10 that all said to stay away. Not a good thing when you see that for ANY company.
Another popular search is "company sucks" where you replace company with the correct company name. This can be a real eye opener on companies and people.
