Capitec bank debiting on different date

Capitec Bank has debited my account twice in one day on a date that was not agreed with them. For the past 9 months I have been experiencing this issue and today it was just the worst. I called them in the morning to reverse the amount, which they did, they then debited a bigger amount 2 bours later. This is totally putting me off my budget and now I cannot do important things I was supposed to do today. I am a very unhappy customer as I asked to speak to the team leader and I was put on hold for an hour.
