Faulty ATM, bad service.

I went to a a Standard Bank ATM in Benmore Shopping Centre because they support Union Pay, so I could withdraw money with my Chinese bank card. I have done this several times before, over several years. This time, however, the ATM failed to eject my cash withdrawal and attempted to reverse the transaction. Over 2 weeks later, the transaction has failed to reverse and my money has still not been returned to my Chinese bank. I have contacted Standard Bank about this, and even visited their Sandton branch. They have attempted to wipe their hands clean of the matter by claiming that I should contact my bank in China. Of course I have done so, and they tell me that I should contact Standard Bank. Standard Bank's ATM escalations people refuse to provide even a reference number since I am not a Standard Bank client. The problem happened because of their ATM! Where is my money Standard Bank?!? On the same day, another person had problems with the same ATMs, at the same time. This is clearly Standard Bank's fault for allowing their faulty ATMs to continue operating. I feel that Standard Bank should take responsibility for their misdeeds and return my funds immediately. It is not my fault that this happened - it is Standard Bank's fault.
