********** activity on my RCS account - gross negligence by RCS!!!!

So it has now been 17 days since ********** activity took place on my RCS card as per my posted review on 01 October 2017. In those 17 days I have received absolutely no feedback until this morning when I emailed quite sternly requesting feedback. All I am told is it can take up to 21 days to resolve. But I must please ensure to still pay my account at the end of the month even if the ********** r5000 is not reversed by then! Meaning I must pay interest on R 5000 *****!!! This is unacceptable !!!! I will not be held liable for interest on a ********** amount or for the ********** amount itself . Once again this is absolutely gross negligence on RCS part and I will be taking this matter further with a lawyer . For a credit company RCS is an absolutely unprofessional company not to mention the general inflated interest they charge. To anyone out there I would not recommend this company at all!! I doubt I will even get a call from this review but my main goal is to get the message out there that RCS is not a company you should ever consider joining .
