Standard Bank is ***********! And by far the worst bank in South Africa

Standard Bank is the slowest most inconvenient bank I've ever dealt with. I received a large amount of funds from overseas as a gift and followed all the rules. They have been holding my finds for almost 30 days without any notice or feedback. I understand they need to confirm funds but if one method isn't working surely banks have different communication methods. I even got in touch with the international bank to make the confirmation and sent standard bank the info. Standard banks have inconvenienced me greatly and hopefully taking my complaints further will teach them a lesson about efficiency.
