Bad service? No service more accurate!!!!!!!!!!!!

I've been trying to cancel my Dad's membership since the beginning of February and today is the first time I've got so far as to speak to a person- who hung up when I started complaining about the pathetic service. I've sent several emails to their advertised addresses with no response, I've spent at least an hour on phone calls that nobody answers or get terminated after 2 minutes, I've contacted via their website stating that I want to cancel a membership and received no response. Eventually I contacted them again this morning giving no reason why I'm contacting them and someone phoned back in an hour, but wanted to put me through to the relevant department to cancel. When I objected that there would probably be no answer she ended the call. Absolutely pathetic, I wouldn't waste my time and money with this bunch of ___________ (fill in the blank space with your own insult)
