Standard Bank - shocking service

For days. DAYS!! I have been trying to get though to the Standard Bank International Inwards Transmissions call centre. "They are experiencing high call volumes." And doing nothing about it. We're an NGO relying on donations from Germany. The funds were transferred by our donor on Tuesday. I have been on hold for hours and hours every day since. Standard Bank is holding onto our money due to their incompetence. We are an educational project supporting orphans and vulnerable children. Standard Bank is *****ing from us. Today is month end and we can't pay our bills. Shocking service!! They are the lowest of the low.
