Discovery Health - very poor systems and service

Towards the end of June 2020, I changed my Bank to Capitec. I made the necessary debit order changes online via the Discovery Health App. However, i overlooked the Vitality rewards and the Healthy Choices refunds. At no stage in the process of making the debit order changes were there any links, or suggestions, or prompts from DH to ensure that associated benefits and banking details should also be altered. As a direct result in excess of R2k has been inadvertently paid to my previous bank account and, according to DH, may not be reversed or refunded to me. Despite requests, and support from my broker, DH refuse to assist nor accept that their, supposedly updated and top of the line, systems are indeed fallible and have proved to be 'customer unfriendly'! All this from a 'customer centric' company. Really. Very poor service and poor systems.
