RCS has no idea what they are doing

June I received a statement from RCS showing I owe them R 1787-44, which I've paid the full amount on 16/07/2015, I still have the proof of payment as well as the statement they've send me. From then I have not received any statements from them...which was fine as I've settled the account! Sunday I received a SMS from them stating I owe them R110, and yesterday a very rude and unprofessional lady called me saying I owe them R1700....I argued this with her, then she changed her mind and said I owe them R 200.<br> It is clear that RCS has no idea what they are doing, and no idea when and how their clients are paying!!! and to top it all they treat their customers like ****!!!! I have all the proof and supporting documents in place and it RCS do not sort this immediately I will take action against they. They are a pathetic company and need to learn how to do their job!!!!<br>
