Not allowed to decrease my limit by Consultant

I was at YDE at The Glen on the 16th April 2016 to decrease my account limit and the consultant I spoke to on the phone (Shannel) informed me that would be impossible and explained that I need to settle my account before I decrease the limit. <br> <br> And this makes no sense as I still have credit available on the account and all I wanted was not to have the credit and have the account limited to R3500. And she could not even give me a valid reason as to why my account went over the limit that I was given without my approval.<br> <br> I would really appreciate it if this could be resolved as this credit needs to be limited. And if Shannel did not know how to handle the matter she should have escalated it to someone else.
