I regret signing up to Discovery Bank every day

I requested to join Discovery Bank early in 2018 when Discovery started advertising. In about mid-June I did the transition from my Discovery credit card to Discovery Bank. I have regretted it ever since. I remember being very clearly told by the call centre agent who did the transfer that the miles would be transferred and new miles programme would be attached to new card. That has not happened. I have been using the new Discovery card for two months with not one mile earned. I usually earned the equivalent of about R350 every month from miles. (And what about the annual miles fee on the previous card - do I get that back pro rata?) I have emailed my complaint over a week ago and never heard anything back. I am struggling to see why anyone would sign up to this bank.
