Virgin Active Red - Parklands Cape Town

A few months ago canelled my virgin red contract and was contacted by a sales person who asked me to put my account on hold for R38pm for 6 months while i decide whether to stay or leave the club. I was advised that I can contact them at any time during the "on hold" period to cancel my contract completely if i wish to do so and the contract would then be cancelled. I did this the other day was was advised only after they cancelled completly that there is a pro rata amount of R200, i disputed this amount as I was not told about an pro rata amounts that i needed to pay when i am ready to cancel my contract. I was then hung up by the consulted (Lunga) and I called back and spoke to Justin Morgan who assured me that R78 (not sure why this amount as i was paying R38pm) would be deducted and no where on my account can he see that R200 would be deducted. Of course over the weekend R200 gets deducted from my account. what I want to know is why when being offered to put my account on hold for R38pm, while being ona month to month basis already, do I have to pay pro rata fees? Why was I not told about this by the first consutant that offered to put my account on hold ? i did not skip any payments, my 1year contract with Virgin red had already come to an end when I was put an "on hold" status. why should I pay pro rata after my contract had already come to an end?
