Poor app planning and no help received.

Bitterly dissapointed. I am currently stuck in the UK and my South African phone number does not work here. Now there is this new app that I can't activate due to needing my number. I cannot even do my banking online anymore as that normally prompts me to approve log on through my app. Just get emails stating old app won't work from end of April. Now I have no access to do payments etc.... absolutely ridiculous that I cannot verify via email or something. You are truly leaving me stranded. Will be leaving capitec ASAP. ..... I have emailed and no reply or solution. Not cool.
