Terrible waste of time and money

I have been a customer with Standard Bank for well over a decade. I have bonds and about 5 different accounts with Standard Bank. Today I got so frustrated that I had to do this. I needed to increase my credit card limit which I need as a matter of emergency. I was on hold for 44 minutes and the call got dropped. Then I called again and I was on hold for 31 minutes, after I spoke to the gentlemen the call got cut again. I called today again at 16h00 I was advised after another 20 minutes of waiting that the lady will take my details down ID and Cell number and she will get someone to contact me within 5 to 10 minutes. I waited almost an hour and no one called. I then phoned again, another gentlemen answered who was not very friendly and told me that I have insurance on my credit card and that he cant help and no matter how many times I said to him that I understand what is next he just kept talking. I asked to speak to his supervisor and he said that I must hold he will get him/her. I waited for 22 minutes with no one coming to the line. I have spend around R300 of airtime as this was urgent and got absolutely no where. I actually can not stand such incompetency, I waited to see if I would get a phone call back and no one called at all. I am really really hoping that someone calls tomorrow otherwise I am going to Standard bank with a different mind set.
