No Service!

On the 30th of March 2016 I had a credit of R410 on my Virgin Active membership. I changed over to Keyfit Membership on the 1st of April 2016. Paid my activation fee, my new card fee, all on the 1st of April 2016. My credit to be app**** to April, May and part June 2016 fees. As from the beginning of April I was denied access as there were queries on my membership. Over and over I was informed it was resolved by the sales person Earl. When I got to the gym on Monday the 2nd of May I was asked if I had a membership as I am not on the system. After investigation I was told that my membership was cancelled. I emailed again on Tuesday the 2nd of May 2016. No response. I eventually call and speak with a Jason, the sales manager, and he says I must see him on Tuesday eve. On Tuesday eve I left my card at reception whilst I attended a class. On my return I was told that Jason was to busy to sort it out, he will contact me. It is now 2 days later again! Who do I contact now to have this resolved?
