Shocking customer service

Last week I reviewe the appalling service I received from Standard Bank which has left me on the credit bureau because of their ineptutide. I got a call from the complaints department with a promise that things would be speedily rectified and that I would get a follow up call on Monday. I knew that I was going to be travelling on Monday, so I asked to be contacted on Tuesday. This was even better, I was told becuase the turnaround time for this matter was 48 hrs (2 working days) and Tuesday would be great. I cancelled the one appointment I had on Tuesday to ensure I was able to take the call no matter we what time during the day it came. Tuesday no call. Yesterday, Wednesday no call. So we'll see where this leaves me, the customer, because I will not be able to take calls today.
