***** on my Game account it's been 3 months no solution

R6,300 has been spent on my Game account without my knowledge. I realized that I didn't receive a monthly statement on April and R700 had been debited instead of R400. I downloaded Game app to see the statement and R6,300 has been spent on the 21 March. I phoned them they gave me an email to send affidavit, copy of my ID and Game card and 3rd of May I did so and I phoned them to make sure they received. Up until today the issue is not resolved instead they still debiting the installment but I reverse it back and now I appear as a bad payer. I've been explaining to each and everyone of them when they phone me about payment and they seem to understand. The worse part is that I'm on errors after they said they will block my card and yet on my Game app everything is on zero (no installment, no available credit and zero owing)
