No Credit Limit Increase

I have been a client of Edgars for the last 15 years, for quite a while I did not use my account during the past 5 years, but started using it again during the last 2 years. I have not had a credit limit increase since I can remember and decided to request one. The Fourways branch assisted me to submit the required documentation last week Friday. The assistant phoned the call centre and was asked to call them back after 2 hours. I went back to Fourways branch today as I have not heard anything from them up to today. I then spent an hour on the phone verify detail and waiting for my limit increase to be approved, only to be told after an hour that the system had not selected me to qualify for an increase. I am an IT consultant and will be billing Edgars for my time being wasted, there are people with much bigger accounts and debt outstanding who gets limit increases. I have been paying my account religiously every month, but apparently my business is not good enough. I will settle and close my account in due course as Edgars (Edcon) is clearly not interested in assisting and keeping their clients happy.
