I want my money back

Good pple on the 26/11/2020 it was my pay day I was happy until when I struggle to log in to my Capitec app to make some payment so I didn't log in the whole day I thought the is something wrong with my phone then decided to go to the branch to tell them I can't go through my app then they advised me to restart my phone I did that but still then the next day again in the morning same thing happend the only sms I received was the notification of my salary only so i called in the morning telling the consultant the same problem so she was rude with me so I decided to go to the bank again so I told them I cannot not use my app so they also advise my to restart I did then I end up deleting the app and install another so my problem was resolved so I went to check my balance it was R128.63 I was like what hell no how come so I printed my statement so it showed that I did cash send from 12:00 on the 26 the same day that I was struggling with my app so how I didn't even receive any notification for cash send money so all my money is gone R750 R 1000 R 550.00 R 100.00 so the lady said to me that the is nothing they can do is my lost Nd I was careless so I won't get my money
