Vitality cashback, what cashbacks?!

When joining Vitality I linked our Dischem and Clicks accounts to our Vitality account in order to receive the cash back benefits on Vitality approved purchases. Three months ago I noticed that we were not receiving these cashbacks. I made an enquiry, they notified me that the accounts were linked, but the payment had not been made and will be in the upcoming month. Still waiting… Every time I follow up the excuse is either that it has been escalated to the manager or that payment will be made with the late claims on the 15th. These excuses have been given to me for almost three months. I follow up on a weekly basis. Vitality simply isn’t what it used to be.
