Discovery agents have **** to me in writing three times and are now ignoring me.

Discovery Vitality agent **** to me in writing in email in January that my DisChem benefit was active when it was not. I acted in good faith and purchased something that should have given me R53 cashback, but no cashback was given.

Upon querying the problem I was told in writing in email in January that I would be manually credited the cashback. I was not.

Upon querying why I did not get the cash back I got 6 months of constant run-around from their help centre with noone willing to take responsibility to actually assist me.

I contacted Discovery on twitter and was told again I would be given a manual credit and it would appear in my Dischem cashback in early June. Early July I still had not received the cashback.

When I queried it (with photo of the Dischem slip showing I had not received the cashback) I was told to check again because the cashback had been given in June. I highlighted the photo showing that the cashback was not there in July. No response for 10 days and now they're actively ignoring me on twitter (both via DM and publicly), so I can only assume they muted me so they didn't have to deal with my complaints any more.

I can't get any information out of anyone by any channel of communication and noone can solve this problem. I've been **** to 3 seperate times and given the run around for 6 straight months. Now the same twitter agent that proudly boasted that they were "passionate about customer service" is ignoring all my requests for feedback.
