BAD CUSTOMER CARE AT CAPITEC BANK

I am very dissapointed with CAPITEC Bank. I bought pre-paid electricity using CAPITEC Banking App. My account was debited ky account twice, but I did not make the second transaction. I noticed when I was closing the App that the balance was less. I checked on the history and I saw the second debit. This is not the first time that this has happened and it is such an inconvinience especialy if you have limited funds in your account, that you have budgeted for something else. I called CAPITEC Bank on both instances, the first time I was told that the banking app is on my phone, I was accused of making the second transaction and I was that there is nothing that CAPITEC can do, they have nothing to do eith the second transaction. The first instance I even ask to speak to the manager who was very rude and she cut the call. I admit Iwas very angry. I was made to feel stupid and a ****. I submitted a a complaint online to CAPITEC Bank and they never called me. On the second instance I called customer care again, I was told that there is nothing they can do. My question was what does CAPITEC do with the complaints from customers regarging the services available on the app, don't they escalate them to the service provider as this for me is unaccetable. I told the person who took my call that if she looks at the time both transaction were made it is excatly the same time, how is that possible. I did not get an answer. I was that they have logged my complaint and someone from CAPITEC Bank will calk, again I have not received a call. CAPITEC does not look after their customers, they don't even investigate the problem. They are good in saying that there is nothing they can do yet this is a sevice they offer on their app. From my experience their customer care is useless as the don't try to assist.
