Bad service received

I app**** for an increase on my Absa credit card in September 2015. I was requested to submit supporting documents which I did. I call today to follow up on this application since I never received an email of call informing me of the status of my application only to find out that no application is shown on the system. The consultant was friendly but not able to assist me with my query. When I challenged him on the pathetic service I getting he dropped the call. This after I waited for 31 minutes to speak to a consultant. This is the worse service I've ever received and I'm sad to say that I'm really disappointed with Absa. I pay them loyally every month and this is what I get in return.
