Funds reserved, but swipe not successful call cent

once again the same problem as in November, swipe card, swipe slip shows not successful at merchant, but still on reserved after 3 days....merchant was not yet credited and my funds have not yet been released back into my card. <br> <br> and once again DCard cannot help and needs to transfer me to FNB Authorisations. What is the use of a Disc Platinum Credit Card with a \dedicated\" call centre?!? <br> <br> Pay more for a service but still, same as in Nov the problem is up to me to rectify. <br> <br> I will downgrade my platinum card as I see no reason to pay more for the same poor service from the call centre. <br> <br> Can you please sort this out, seems like Discovery Card and FNB has issues with service as the \"middle man\" and cannot help at all when this happens second time round!<br> <br> Sort out please!
