Discovery and Vitality a Necessary Evil

I phoned Vitality Contact Centre on 7 Nov 2018, because I have not received my Cash Back Rewards for Healthy Foods in my bank account since 01 Oct 2018. Also, the amounts on the Website (under my profile) is not the same as was paid into my bank account on 01 Oct 2018, so I also queried that. I was given a Ref no. ********** 437 and a commitment from Vitality that my query will be resolved within 5-7 days. It is 20 Nov (today) and I am still waiting for my money to be paid into my bank account. So, I called again today and was given another Ref no ********** 993 for the same query that the previous helpdesk assistant apparently did not log and another promise that my call will be escalated (again). I just received an email from No Reply at Vitality, saying that my query from this morning will take 5 days to be resolved!? So I phoned again this afternoon, needless to say it is all empty promised and no service. Discovery and Vitality is a necessary evil. They owe me R759.26 in total and it has been overdue since September 2018. Rather disgusting service.
