Standard banks bad service!!

I phoned and asked to increase my credit card limit. They said someone will call me with in 2 to 3 working days. 3 working days later I had to phone them because I still have not received a call. I phoned the morning and they told me someone will phone me the same day but if they don't I can call the afternoon again. To my surprise I had to phone them just to hear that they can't help me I will have to phone the next day. So I phoned again the next day.....and guess what? They can't help me today because that section is closed today. Wow what a surprise! This is bad service at its best!!! Thank you Standard bank!
