Nedbank Platinum Card unresolved Query - Despite 2 escalations.

This complaint is with regard to the Nedbank Amex Platinum Card. For some unknown reason since January, online card payments have not pulled through to my Amex rewards account. I queried them and they after their investigation they manually credited my Platinum account with the incorrect number of rewards. They closed the query. I had to contacted them again to recheck their calculation and they said that they could see the error was that they had used the calculation for a Gold Card and not Platinum card. There are 2 Points for every R5 on Gold and 3 Points for every R5 on Platinum. The next day I get another SMS saying _ Please note the ratio 5 and the accelerated points are divided by 2 from the calculated points. The case has been resolved. Nedbank Team ***. Whichever genius created that reply either does not know the product or did not bother to get the facts of what the initial or subsequent reopening of the query was about. In any event I do not understand what that SMS meant. If Nedbank want to take the time to try to resolve this they can look at the Case number ***9 and phone me on my cell number that they should have on record.
