Customer service

Im in a situation where i currently cant receive any notifications on my current sim linked to my tymebank account. I called the customer service to change my number and was told U can change it via the app but my selfie verification is not working either, was then told to go to tymebank kiosk and was provided spots to find it. I've been to the places where I was told I would find these kiosks, got there and not one of them has a kiosk. So im basically stuck i cant do any online banking or payments as im not receiving messages on my current sim. To top it up my bank card is not reading anymore by a atm or by swiping at a till. So im stuck there to as im not finding a kiosk to get a new card and calling customer service is not really proving helpful as I get provided with info that is not accurate. Needless to say its been a frustrating couple of days and I still have no solution.
