Game stores *****

On the 6th of September I paid R300 towards my game account via online payment. The money went out of my bank account and when I check on their Game store app it said paid then a day later is said "reversed" but the money never paid into my account. I went to the store with my bank statement to complain. The lady who was helping me was also surprised because this affects my credit rating too. She put me on call with the financial department and they asked me to send my bank statement through to them and I did and they said they will fix but to date they still have not fixes it and they keep calling saying I did not pay my monthly fee. They have instead added call fees, interest, letter fees! I feel like I have been ******!!!
