Pathetic RCS Makro service

RCS Makro is useless on 26/10/2017 I received a the following sms:

**MR GOVENDER, we'd like to give you an exclusive R250 back on your Makro Credit Card with your next purchase of R500 or more at Makro. Don't miss out, offer ends 05 Nov. You have R9979 to spend as at 23/10. Credit will reflect on your Nov statement. T&C's apply. Opt-out No**

So I purchased on that day for R900 but as its states above credit will reflect on November statement ,it is now 07/2018 a whole 9 months later and still no credit. I have been calling customer care from December 2017 and till to day no one can assist me in crediting my account .I can't understanding how no one knows how to credit a account but your system knows how to automatically bill charges to my account every month. As you will see on your system I have made my previous payments on time and only left the balance of R250 which should have been credited.

I have made many attempts to try and reslove this query with RCS Managers Abegail George and Nuraan Williams but still I have your customer care agents calling to tell me to make payment on a balance that should not be in my account but no agents calling to tell me that my account is balanced off.

It is surprising how it clearly shows on my account that I should be credited but no one not even Mangers know how to do it ! I have not purchased anything from Makro since 26/10/2017 and will not in future ,I have already advised friends and family not to get RCS cards when they call ,to expiernce the very very very poor service that RCS proudly provides.
