RCS over charging me

I logged a complaint over 3 weeks ago,regarding RCS over charging me for a Game account that I've been paying for the past 5 years for Items I bought to the value of R10 000 but have already over R50 000 but no one is saying anything from RCS when ever I query this as it looks like there's *****ule activity on my account, no one is investigating it, no one is communicating anything despite of all complaints logged also on email.Very disappointed about how these complaints have been ignorered
