Delayed international payment

I have had the worst experience with standard bank lately. I have called the international payments dept, and no one answers the calls. I have emailed and only received automated responses saying Refilwe Moepye is attending to my request but no one has communicated anything to me. I recently relocated to New Zealand and I paid rent and deposit through International payments on the banking app. I did this a week ago and received an email to confirm initiation of the transaction. The estate agent let me move in anticipating the funds to be in their account in 2 days. It's been a week now and the funds are still on my account and no one has bothered to respond toy communication attempts. I'm at the verge of being kicked out, with an 11yo child, in a foreign land, all thanks to standard bank.
