Stuck overseas and Vodacom refuses to help activate roaming

I asked Vodacom on Twitter to assist me in activating my SMS roaming for online banking as I’m overseas and obviously won’t be able to travel for many months due to the pandemic. They asked me some security questions and then said I failed because I couldn’t remember the last date of recharge (they send multiple texts after recharging which I obviously delete!!) so the consultant told me to GO TO A VODACOM STORE?? From overseas?? I then sent multiple screenshots proving that I am the owner of the cellphone number. Then I woke up at 3am my time because of the time difference hoping that they would respond to my DMs but they show no urgency to help me at all. I was then asked more security questions which I easily answered and then I never received a response back. Now I’m stuck overseas with no help from Vodacom and cannot access my funds as I’m not receiving OTP texts.
