card stopped and transactions went through after s

On 14 aug 18h30 i phoned capitec *** to stop my card that was not returned to me from the atm. I phoned at18h40 again to confirm if card was stopped, both calls was confirmed that card was stopped. After 18h40 transactions for about R500 went through with my card. This is unacceptable for me. I phoned immediately to stop my card and now someone used my card after that. I did phoned in 3 times for feedback, i dont get any answers . I expect to get feedback asap and i expect refund for those transactions . I feel the trust i have in capitec is affected . If this matter is not handled very urgently i will have to decide if i can continue banking with capitec . My reference nummers : ***4, ***3, ***9
