Unsatisfied by Capitec Bank

On the 30th June 2020 there was a money that was sent to me via mobile transfers. Then on the 21 July 2020 I received an sms notification saying payment correction which is equivalent to that amount that was being transferred on the 30 of June. I didn't take it into so consideration till the time my brother transferred me some money but when I checked the balance it was R0. I went to the branch and they told me that on the 30 June 2020 the money was transferred twice into my account which I didn't notice. It was wasn't my error but capitec bank's fault. All this is heppening without my consultation and that time I needed money I was in Khayelitsha and the situation was so bad n I was just stucked there. I called the customer care services and the person I spoke to was Miriam Ref no ***5 explaining all the situation to her which I hope it's being recorded as promised. She said she is going to email her manager. Then around 6pm same day Monida called me Ref no ***5 and said she has had what happened and she understands that it's Capitec's fault but they can't do otherwise they are very sorry and I still have to pay capitec bank the rest of the money. This came up after I requested her to reverse they money as I needed it urgently and I even requested that let's make arrangements to pay it but she refused. I have some questions to ask but I do not know who.m.

1. How come that the incident accurs on the 30 June 2020 and the correction is made on the 21 July 2020? 2. How come that Capitec bank can go to my profile without my concern and make deductions without contacting me or make me aware? 3. Do not I have a right to negotiate the payment back as I do have family to take and to just lose so much money unbudgeted can make the situation worse? 4. Where did that money come from that entered twice to my account as from the person who transferred just appears once? 5. What does Capitec think of respect to the clients? I would say if Capitec bank is this the way of treating your clients, you are too backwards
