Abroad With No Access To My Funds

I did jot realise when travelling abroad that it was required to notify the Bank. After using my card in New York for the first time my account was frozen. I sent an email to customer service 3 days ago. I was then requested to supply and answer security questions, which I immediately did. It is now day 2 and I have still not received a response or access to my bank account. Nice, a 100k trip turned into a nightmare, well done Standard Bank!
