The most useless credit process facilities

I have waited 3 weeks for an increase on a credit limit. There is no number or contact details for the department that approves the credit or loads the credit. I have gone to another bank (ABSA) and they helped me within 24hrs. <br> <br> I am disgusted to be banking with FNB as they are supposed to be my bank that i can count on and trust. <br> <br> I am still waiting for the credit increase and have no idea when the process will be completed.
