Poor client service

Capitec bank is so unpredictable, they deducted money from my account, I can't even see in my statement and App but only on the notification sms that inform about the money that is being deducted . I called the bank and they keep me on hold for 30 minutes or more. I am still not happy with the way I lost my money, I want my money back from them. I cannot even be able to reverse it because it is not showing on the statement and on App, Customer service is very bad. Please advise whether what must I do because I have no where to go, it was my last cent and I can't even visit relatives because of this lockdown for Covid-19. I will be very grateful if you can be able to assist.

Thank you
