Unfair business practices

Good morning Please help me terminate my membership with Virgin Active. My name is Martin Ndhlovu, been a member of Germiston Virgin Active from 2004 ( membership card number ***) Back in 2004, I signed 24 months contract, which had expired long ago. After which the membership had continued on month on month basis (pay as you go) Currently, I am experiencing financial difficulties, hence I can't continue paying monthly gym fee, as results, I went to Germiston club to inform the staff that I intend to terminate my membership. Firstly, I was told, I needed to pay for cancellation of my contract, which I explain that I had no standing contract since it expired in 2006. I was then given number to call customer care at virgin active head office. I did call and explain to the staff my problem, was told to pay gym fee for month of October. It is strange because, when you had not payed for the current month, you are denied access to the club on the 7th of every month. And since my membership was on month to month basis, I had expected the membership to terminate, but instead I was told, I should pay (R 430) for my contract to cancel. Which I disputed, and was then told to pay a cancellation fee. My problem, it seem like I would be contracted to Virgin Active for life, my contract expired many years ago, I had been paying and giving them business because I enjoyed their gym. The 24 months contract had ended, yet I must still pay for cancellation fee, and I can't stop them making debt on monthly basis for none existing contract? Please help me, I am finding hard to deal with the staff at virgin active My contact number *** Thanking you in anticipation. Martin Ndhlovu
