Capitec's useless service

Had the worst experience at Capitec Brixton Money went out of my account yesterday the 1st of July I didn't notice because no message came through and the app kept kicking me out I ignored it and today when I bought airtime I realized that there's money missing I went to the Brixton Branch to querie it they then said to me that it was done online and they can't reverse they can only call customer care to escalate it then they'll be able to tell me when if it would be returned and it's not the first time all the time small amounts like unde R10 went out as fees or whatever so I ignored but a whole R603 is just too much useless bank I am seriously changing my bank
