Shaw Academy don't take care of their members.

Last year Shaw Academy made an error on my billing and gifted me with a free lifetime membership. I then embarked on my course and am halfway through two courses. Last week having tried to log in - I discovered that I have been removed from their membership completely - in fact, I am logged out and my account of a few years is now not found on their membership at all. I have logged 3 queries - since Friday last week with no response from them other than their automated general response promising a reply in 48 hours. Meanwhile, my studies are on hold. Customer service? What customer service?
