ABSA online sucks

At the end of 2017 I was informed by my online banking that ABSA is upgrading it security and that I need to install their app on my cellphone to improve security. I did what was asked as security is very important especially when doing online banking. Well ABSA your new security sucks! Since installing the app doing an online purchase or payment has become a tedious job. Something that took 30 seconds to do now takes hours and best is every-time you send me an sms to confirm my logon I get charged. And where previously I had almost no sms fees to pay I now have a lot. I think you were less interested in keeping my banking secure and more interested in lining your pockets! Oh and the excuse I am given when a payment doesn't go through, your signal is weak and we were unable to process or connect to the app. Funny how my signal strength is 100% when you send me this. And how all the other websites refresh in seconds while ABSA online takes minutes.
