Unsatisfied with capitec

Got something that's been trying to debit from my account as i see it its an online purchase bc it says my transaction has been declined due to limit and charges on the other side are going out from the amount that i have. I have gone to the bank they say i have subscription of something but i don't and they check my emeils and said its flo a period tracker that I've been using for a long time they said ive upgraded and then cancelled it and i ask why is it deducting my money I'm thinking of going there and change the card when i left them was not happy at all with their service and the consultant who was helping me has a problem with listening bc u say this and he says the opposite I've been with capitec for more than 10 yrs can't change now
