How can ABSA expect me to hold on for a hour 10 mi

I tried to phone ABSA card division Friday to find out the progress of increase in a credit limit. The call lasted 20 minutes where after the call was ended or dropped. I can't say how this frustrated me. On Saturday I tried again this time the call was 19 minutes and 3 seconds where after I hanged up. I tried again today and decided I will hold on until the call gets answered. I gave up after 30 minutes.<br> This is unacceptable how a company can expect clients to hold on for such a long time they can't use an excuse they are experiencing high call volume. If this happens every day they sure should be doing something about it? The first step would be to inform the client he/she would be holding on for 30 minutes and longer. You can not inform a client he will be holding on longer than 5 minutes and are not able to answer within a reasonable time. I don't see answering a call longer than 10 minutes reasonable. I hope somebody with authority can attend to this problem as it surely is a major problem in their call system.<br>
