Dissatisfied and disappointed with service

Though I've often received exceptional service from Discovery, feel I must express my dissatisfaction and dissapointment in the way they have handled my query on oustanding drive reward which I have reported 3 times. Each time I call to enquire on why the outstanding reward from goal earned is not issued, I have to repeat my story which is tiring, time consuming and costly in airtime. Since Discovery active rewards migrated to the new discovery open application, there has been a delay in rewards being updated. I tried to be patient to allow for the glitches in system. Now that it seems to be working fine,I still have 1 reward which is still outstanding. Last week I was promised it would be issued this week but that did not happen. When I called in to enquire,I had to explain the whole story as if new. The worst part of it,I was put on hold while the matter was being verified with the manager and the call got disconnected due to other calls coming through on my phone. Yet the agent I was dealing with never bothered to call me back to give me an update in the resolution of this query. I'm really dissapointed by this type of service. I would appreciate a response from Discovery Insure confirming the resolution of my outstanding reward which was telephonically acknowledged by the 3 agents I had spoken with and the issue of that reward. Thank you.
