Credit Limit Increase and New Protection Plan

I have been a client of Absa for more than 30 years and have just experienced the worst service from 2 call centres. Firstly I need to arrange for a protection plan on my my car finance at Absa. I have been trying to get hold of someone at the call centre to assist me but was holding on forever. <br> I have app**** online last week to increase my credit card limit and immediately receive an online reponse that it was approved in principle. I have tried numerous times this morning to get hold of someone at the call centre without any success as I was holding on for more than 20 minutes.<br> I am really frustrated as it seems that I cannot get service anywhere.
