Beware absa app

Loaded the absa app but now i an barred from paying accounts, loading airtime ect because they have a 2 step system and they are unable to connect to my app. I have checked that software, connection are all in order. Logged a fault with them c-***5 and they blane wifi, my phone, ne, Vodacom but the problem lies with them and their gr2 it engineers. They have niw ghosted me and i will be forced to close my account after 30yrs and move to another bank as carrying cash around to pay accounts is not feasible anymore.
