Service is terrible!

I am utterly disappointed with Standard Banks services! I called in last week to increase the limit on my credit card, firstly the guy who answered (didn't get his name) he gave me an email address and told me to send through my documents as my salary doesn't get paid into Standardbank. I respect that completely, I sent through the required documents. Called back about 2 hours later, waited on the phone after hearing the disclaimer twice, only to get told that the email has not reached them yet. The reason is because they use 1 email for all possible documents for all of its clients. Then I called back another 2 hours later, heard the disclaimer again, waited for 15 minutes for the agent to retrieve my documents, once she located it we went through the process and then it got referred as I need to send through a PR letter from the ***** department. I was told that they will call me, I am still to hear from them and I am wondering if anyone is going to actually retrieve that letter of mine from their mail and call me. So my limit still hasn't been increased and still no sign of Standard bank.
