Access denied/transfer fee R190

Contract Number:***; Membership no:***5 /discovery no:***<br> Virginactive deducts the membership fees in advance on the first of each month.My debit was deducted for my premier membership on 01/02/2016.I then during the first week of February that my membership be changed to a club membership from 01/03/2016.I was then notified that I would have to pay R190. The Following week I received notification that my account was in arrears.I disputed it as my change should only be effective from 01/03/2016 and that I already paid my premier membership fee for February I was informed by Natasha that the R190 becomes payable immediately and therefore reflects as arrears.So even though I paid my membership in February I was Denied access on the 25 Of February as I didnt pay the Ridiculous admin R190.00fee.I then contacted Natasha again, she advised that they would waive the arrears fee.I then went to the gym again on 27/02/2016 and was denied access again as my account still reflected in arrears. I then had to contact the call centre and email the information to Fatima who then only agreed that the admin fee would be waived.Surely this is unfair billing as I paid for February.
