Virgin Active South Africa
Money deducted after closing membership

I and my wife were member of Virgin Active and we have closed our account dated 28th Jan 2013.
I paid Zar 307.00 for my account closure and Zar 136.00 for my wife's account closure.
But after closing account also Amount Zar 113.80 is deducted for me and same amount deducted for my wife from my FNB account on 1st Feb 2013.
I think there might be some mistake but this amount should be reversed and Virgin active should take care that from hence onwards they should not deduct any amount from my account for me and wife.
