Horrific international transfer with standard bank

I have received appalling service from standard bank regarding an international payment. I made an international payment 2 weeks ago for a rental deposit and the payment has still not gone through. I decided to give it a few days, knowing that international payments can take some time, but eventually I followed up last week Thursday. I was told that payment was on hold with the intermediary bank but up till now they are yet to get back to me with a resolution despite my repeated emails explaining that this is urgent. I am honestly horrified by their lack of any sense of urgency. Yet they advertise how easy and quick their international transfers are. I would urge anyone to think twice before making any important international payments through standard bank.
