I recently immigrated and need to change my details with Standard Bank. My OTPs come through to my email already, but the bank recently phoned my ex employer to check on "suspicious card transactions" even though all my cards are set up for international use. I want to change my contact details, but obviously cannot go into the bank to do that. How do I go about this? The lady I spoke to RE the transactions promised to email me the info, but hasn't done this.
