Bad service ever

someone was able to buy airtime with my card almost R1000 i lost due to this. i went to Capitec bank and they change the card but this thing did not stop at all, i went again and they said they pay back the money now they calling me that they wont pay. i almost transfer my debit orders to Capitec i'm glad i did not, and tomorrow i'm closing Capitec account because i cant bank with the bank that i do not trust
