Disgruntled client

I have paid up my Game account and haven’t bought anything for over a year. I’ve replaced my card recently and the consultant advised that I will pay a fee of R50 which I didn’t mind paying. I received a statement this month and to my surprise I have a balance of R107,99. I haven’t even made a purchase. So they are charging R50,44 for a card replacement, an interest adjustment of R23,22 ( bearing in mind I haven’t made a purchase), monthly service fee of R29 ( again I haven’t made a purchase) another interest charge of R1,30 and a customer protection plan fee of R4,04 equaling the R107, 99. I am totally disgusted and an extremely dissatisfied customer at this stage. If they don’t reverse these fees I will definitely close my acvount
