I Give up

On 30 or 31 August 2022 I bought data. My data account was not topped up, I decided to call service provider but I was referred to my bank. I phoned client care, I went to the branch several times until I decided to give up and let go for the sake of my mental well-being. Fairly recently Capitec send me messages that I'm over indebted and unilaterally reduced my Access Facility to Zero. Who told them that I am over indebted? What calculations did they perform to arrive to that conclusion? Lastly, today I phoned client care to request a paid up letter, I was informed that I need to log into my app for verification, my App was not opening, I asked whether there is not other way we can do verification, other banks ask security questions. I was told that there is no way. So clients who do not have an app cannot be assisted by Client care. So I think that's it between me and Capitec, I don't think I'll ever get things done right for me. I must just look for happiness elsewhere.
