Victim of ***** due to RCS/Game poor online security measures

Good day, I wish to express my dissatisfaction with Game and RCS. Unfortunately I have become a victim of ***** due to the extremely poor online security measures they have in place. Someone was able to login into my account and withdraw money without any notification to me or validating any of my identification. I also did not receive any notifications about this transaction/s. I have since, sent the relevant documents to the ***** department to have this matter investigated and for my account to be sorted and put back into good standing. I am still unable to login into the Game Credit App to check my balance or the transactions because it was hacked and no one is able to assist me with this. Who is in responsible for the Game Credit App and is able to view what is going on?
