Frustrating ABSA Cellphone banking App

ABSA has improved the cellphone banking app and we are grateful because its easier to use. The biggest problem i am having is that somehow the app does not synchronize with my profile. The error message is " Allias deviceID does not match the credential deviceID". I have uninstalled the app more than 10 times with the hope that i can fix this problem. I have been to the bank 3 times to fix this issue. The first time i went, an e-mail was sent to IT to fix the problem and yes, the problem was fixed within hours. The second and third time i went i was given a reset password which also worked...thank you. The problem here is that i cant keep going to the bank to fix this. The whole point of cellphone and internet banking is so that we don't always go into the branches. IT or someone needs to find a permanent solution to the "DeviceID" problem as the app itself is very inconveniencing. Create or find better Software and upgrade the App again if need be.
