Standard Bank ***** division

All 3 of my sons received inheritance payments from Holland in the week of 5 June 2023. All 3 bank with Standard Bank. Their ***** division froze only my youngest son’s account. 6 weeks later it is still blocked. Nobody answers their phones or emails. We have emailed the proof of payment from the Inwards division and proof of tax paid in Holland repeatedly and yet we are ignored. We are now desperate! Have spent hours in branches to be told they can’t help? So who can??? Stay away from this gross incompetence!!!
