Disgusted in the service from Standard Bank

For the past 2 months I have been constantly calling standard bank for assistance with my credit card, all I wanted to do was increase my credit card limit and not one consultant could assist me. I keep getting sent from pillar to post and my call kept being transferred from one department to another only for each consultant to tell me that they can not assist me. I've been told that I have an outstanding card on my name and that's what seems to be the problem, when I tell them I do not have any other card with standard bank it's like they just hit a blank. I've been told they will escalate this issue to management and I will receive a call, it's been 4 weeks and no call, I have even called standard bank 3 more times and still no help!

This is not the first time that I have received such terrible service from Standard Bank. It's absolutely pathetic and so frustrating!!
