Thieving and *********** RCS

I have been fighting with members of your staff for more than 2 months already. My account should have been settled up but someone reversed a cash payment of R6350 and reposted it as R3350, because of this I am expected to pay until someone at RCS gets their act together and sorts out my account. I have spoken to multiple people about this and get assured the matter will be looked at and they have made notes on my account about the issues but no one ever calls back except to ask for payment. I want to speak to someone who can assist me and not antagonize me further by asking me to make payment on an account that should be settled already. I have sent through my receipt as proof of payment showing the payment of R6350 in cash multiple times, but due to the staggering incompetence of RCS nothing has been done nor has a finger been lifted to sort my account out!
