RCS unacceptable POOR service!

I worked out of country for that last couple of years and in March I received a call from RCS that I need to pay my Cape Union Mart RCS account. I advised the consultant that called me that I will pay my account upon my return to South Africa end off April 2019. I went to the Cape Union store in the Grove Mall on 4 May and asked to pay my account, the cashier then said my installment is R450. I asked for the total outstanding to settle my account as per my agreement. I then settled the account in full for the amount of R9100. The in store lady told me the money is not yet reflecting on my account and will only do so in 24 hours because its a big amount. After 24 hours the money still did not reflect. When we called RCS to ask what is going on I was advised that my account with them is deactivated because the account was handed over, RCS also told me that the Cape Union Mart store should never have given me any amount to pay because the account was handed over. I have made about 10 calls since then and not one person at RCS are able to help me. I asked for records regarding the arrangement I made that I will settle the account upon my return and nothing can be provide. The call centre agents at RCS even say they understand my frustration and say they do not have any power to assist me in the matter their hands are tied. They have escalated the matter about 3 times not to management who apparently have the power to help me and I do not get any call back whatsoever from them. I am stuck in this situation and no one from RCS can help me, I really have not experienced such poor service in my life. I will make it my mission to shame the name off RCS on any possible social media platform until this matter gets resolved. I will not pay any legal fees to anybody because of the incompetence of the RCS group to update their systems with an arrangement I made.
