Disgusted with absa

I am highly disappointed at the way iv been treated by absa and so called management. I called over a month ago notifying them I was unable to transact via internet banking due to my not being able to get verification codes on my absa app, I was told I would be reverted to the previous method of having a prompt come up on my phone and continue to transact that way. I was told to wait 24 hrs for this to become effective, over a month later and I still am unable to transact. The app does not work. I called again on Tuesday and was told they would query it and wait another 24 hrs, nothing happened. I decided to escalate the matter to a supervisor Kamogelo who assured me I would be assured today and get feedback by 13:00pm today. He never called, when I called later this afternoon after 4 I was told he had knocked off. What kind of Mickey Mouse service is Absa playing at? Iv been told to call back on Monday, that's utter b.s after being told I would be given feedback at 13:00pm. I don't even want kamogelo to call me at this stage. I'm seriously over the service I've gotten at absa. I bet other banks don't treat their customers this way, especially with absa having come up with a new banner and new marketing strategy. I really don't see how you can redeem yourselves after this. I'm frustrated and utterly ****ed off for lack of a better word
