Virgin active sucks!!!

I have a majour issue - i have been a client of Virgin active for over 7 years now, I visited the gym twice last year and they had no electricity, They advised me that they will still add it as a visit as i signed their booklet. I then went twice this year to the Boulders mall virgin active (around 13:55) i was told that they are closed, the gym only closes at 14:00 so i had 5 minutes more to swipe my card. I lodged a complaint over 4 weeks ago with the call centre - i was told that the manager will investigate and come back to me within 4 days - it has since been 4 weeks and no feedback - today i get an email that my membership is now cancelled with Virgin active. You guys suck and your service sucks as well. I am going to take this to the media as i have the call recording where your agent promised me that the manager will get back to me. If you manager has such poor customer service - what for the staff!!!!!!
