Poor engagement and service received

My Discovery credit card expired the 1st November 2019 at which i did not receive notification of a new one to be issued to me. I send a mail to discovery card after been on the line for too long and phone got disconnected. The following reference number was provided ***. I have followed on this reference number via email a couple of times yet as of today 26th November i did not receive further communication from Discovery regarding arrangements for the renewal of my card. Very disappointing
