Bad customer service and incorrect information

I joined virgin active northgate on the 29th of Sept 2017(Friday) and went to cancel it on the 6 Oct 2017 Friday but i was given incorrect information by an employee at Virgin active by the name of Thabiso and Silvia. I was rudely told to pay an amount or R325 for them to be able to cancel my contract. Well by law and according to my contract, i was still able to cancel it without paying any fees as long as it is within 5 working days EXCLUDING the day i signed my contract. So my 5th day was on friday(6 sept 2017). Bt according to 'their' calculations it was my 6th day. This shows that employees at virgin active do not understand their work, they tell people incorrect information and want them to pay for things that are not there. To them i might have appeared clueless but i know my reasearch. Martina from Virgin active northgate and consultants from the call center explained to me how cancellations work and i understood. But according to Thabiso and Silvia, its different. This will make our image look bad. You will lose customers and never recover from there with such service. This below is from the terms and conditions of cancellations
