No access to banking app when you travel internationally & get a new phone

I have always loved being with Capitec, but since I have been struggling to get them to help me the past 2 weeks I am feeling really frustrated and irritated with their service. I've been in Ireland and haven't been able to travel back to SA because of the Covid-19. I got a new phone & now I am not able to use my banking app anymore. I have been on the phone several times in the past 2 weeks but no one has been able to help me! Either I get a generic e-mail or a "sorry we can't help you with that". How can someone travelling internationally NOT BE ABLE to access THEIR FUNDS? My husband is with ABSA and he was able to resolve his issue in 1 minute. I am very disgusted as I have bills to pay and money to transfer but I won't be able to do so until I get back to SA; which will probably only be in December. Wish I was with another bank... Capitec is not international friendly - at all.
