Bad call center not doing there Job correct

Good day So my contract comes to an end April and I called to log the cancellation on the 26/02/2018 as it stipulates you have to give a full months’ notice. When I called I spoke to a guy named Jasten on the 26/02/2018 he said if I want to cancel now there will only be a penalty fee of R280. And it will be taken off debit order gave him all my details and I asked for the full account to be cancelled, me my son and my husband, all is on my name. Yesterday this lady calls me Poucha and said my account is in arrears I said no I cancelled it, so she said this Jasten only cancelled my account not my husband or my sons account. And she said to cancel all thee will be R260 pp and I said HELL NO!!!!! I’m not paying that, Jasten said it will be R280 to cancel that’s what I will pay. VIRGIN ACTIVE you need to get your call centre sorted and get this account closed asap I’m not paying you anything more, if Jasten made a mistake then he can pay for it. Just cancel my account I’m done with Virgen active and will never revere anyone to you.
