Discovery Vitality complaint

I really had a hard time this past few months with Discovery, especially their Vitality apartment. Firstly I emailed Discovery Vitality in the beginning of the year to cancel my Vitality membership (the date was 16th of March 2023). I then found out that the same email adres they emailed me from does not work anymore as they have closed down many of their email addresses . The day after that I phoned to cancel the membership, the lady working for Discovery told me the membership was cancelled. A few months later I was debited for the monthly premium of Vitality. In August my Vitality membership was cancelled upon switching medical aids due to work. They then still withdrew the premium from my bank account for September and October after the cancellation was done, but the cherry on the cake was that they deducted an amount of R987 in November for Vitality as they called it a “back payment”. After 5 phone calls and about 4 weeks of struggling my refund was done. They also stoped the debit order AGAIN. On the 27th of December the same amount was deducted from my bank account. After I phoned them again, the lady told me that they don’t see the transaction but she has logged a request for it to be processed again to be paid back. I am really not impressed with Discovery and their service. Someone from Momentum helped me to get hold of Discovery. Very disappointed with Discovery’s client service. Really fed up!!!!!!
