Last month I had an issue of a card transaction that went off my account without my consent and that was resolved, old card was blocked and I was given a new card. again there's another company that keeps on taking R278 on my account that I'm no aware off. I thought this kind of transactions were blocked. and I cannot keep on going to the branch because I'm covid 19 patient.
