Appaling Service

I am totally disappointed with the service i have received thus far. i have and 90/10 day account and i last withdrew money from it on 12 Jan I know that every month 10% is available . i called on 12 Jan and a lady i spoke to assumed that the funds will be available on 12 Feb without even checking on the system. On the 12 Feb it wasn't available a called your call center again and the guy mentioned that it will be available on the 26 Feb, i check yesterday and today, and still nothing. I place a notice and i mentioned to the person and he advised that it won't affect the amount available. i called today and spoke to Zandile who took the time to find out and she advised that "The system is confused because of the notice period, therefore, no funds are available". Now tell me whose fault is this and i now need the 10 percent now because its not my fault that i was advised. if this is not rectified, I will be canceling my whole account and moving it to FNB. Please have a look at my profile and you will notice that I am not an ordinary customer unless you don't care.
