Jet ***** not clothing!!!

We settled our account on the 11th of september last year. Contacted someone for a settlement letter. Never got a reply so we assumed it was closed. We now recieved a statement for R600 and some idd for club fees. Firstley when we opened the account the woman asked if we wanted the club fees and we said no. Now I qiaried it and they willing to give us a R180 discount in the R600 owed. Inhave asked for a copy of our enrolment letter and been given the runaround. Now I recieve an email stating the matter has been settled!!! What the actual hell. I want someone from headoffice to handle this as I am fed up and will be bringing my lawyer into this as well as social media to name and shame Jet Clothing if I have to.
