Discovery Vitality - No Cashbacks rewards since May 2020

This is the final straw, i have been with Discovery now for a couple of years, and have mostly recieved very good service, i have almost the entire dscovery suite, and really make use of the products.

But the customer service i've been experiencing for the last 3 months now are just really bad, i cant even understand how a massive company such as Discovery can continue to treat customers this way.

I logged a query mid December 2020, stating that i have not received Cashback rewards since May 2020, i thought something might have changed, and i logged to make them aware of this issue, i didnt get any response for that query that i logged, so i re-logged another query in the 1st week of January 2021, after about 2 weeks i received a mail stating they are still investigating and will contact me, about a week went by, and i called the call center and was told that my banking details have changed, and that is why they never paid out (My banking details have been the same since 2009, no change at all) i told the consultant nothings changed, so he sends me a mail to update my banking details, which i responded to him.

15th January 2021 - I mailed to ask for an update - No feedback 21st January 2021 - I mailed to ask for and update - No feedback I then get a mail on the 12th February 2021 saying i need to update my banking details (Again) to which i responded and updated the details AGAIN!

17th February i get another mail from Vitality saying they are investigating the query, and they notice my banking details have changed, can i please complete the attached document to update banking details (AGAIN!) To which i reply with the orignal attachments and send everything off.

I then get called by a consultant stating that "She will personall deal my query" and that the payments team will process the Cashback and i should get it within 24-48hours in my account.

Another week goes by, i get a generic mail saying the finance team is investigating and they will contact me shortly.

Eventually on monday the 1st of March i sent a mail copying all the original mails asking for feedback, to date i have not recieved a call, nor an email acknowledging my last mail.

So far ive been told that the cashback amount has just been processed, it will reflect within 24-48 Hours byt 3 different people.

Ive been told by 5 different people that they will be dealing this matter personally, (They each called once and never again)

Ive been informed by a number of different consultants that they have identified the issue, and have already resolved it so it wont happen again.

Just as a side note, it is now March 2021, and i have not received Cashbacks for the last 6 months of 2020, nor have i received anything yet for 2021.

This customer service is really not what i would expect from a large company like Discovery at all.
