No Feedback on Credit Card Upgrade

I was contacted on the 15th of March 2016 to offer a credit card upgrade for my Gold to Platinum card. I accepted the offer and we did everything telephonically. I was advised that the card would be sent to the branch of my choice after which I'll receive an SMS to confirm the delivery of the card.<br> <br> To date I have had no response about the card upgrade nor have I been notified of it being ready for collection. I have sent an email to the card division for assistance (reference number 87624) and I sent a message through my internet banking platform for assistance. No response.<br> <br> I would greatly appreciate it if someone can please look into this issue to see whether the card IS being delivered and provide an estimated time when the card will be delivered.
