Stuck in a foreign country

I am absolutely appalled with the level of service I have received from standard bank. I am traveling abroad and was expecting to actually rely on my bank to support me. Before I departed I made sure I changed my otp to email notifications. I also used my banking app to allow my card to be used abroad. I have emails to Standard Bank as none of my transactions or apps are going through. I have no way of contacting them other than email. This was all supposed to have been sorted out before my trip and I was assured it was. This has really made my experience in a foreign country really stressful. I am strapped for cash and can’t even use my phone to call an Uber. I will definitely be changing banks and would advise anyone not to use Standard Bank when traveling abroad. I would give them a negative rating if I could.
