Poor service

My credit card expires, ABSA is obviously aware of this as they issued me with a new one. The old card is not removed from my account. I phone the credit card department to say I want this removed as it is no longer an active card or account. They put me through to the internet banking department, literally hold on for 12 minutes, internet banking says the account cannot be de-linked online and I will have to go into a branch to de-link. So this makes no sense. The agent says they cannot make changes to my profile, I have to be in the bank to do that. But then how did they add another credit card and account to my name without talking to me about it? Obviously they made that change to my profile. I ask the Internet banking agent why, she says she cannot talk on behalf of the credit card department but she knows they can't. So she puts me through to the credit card department again. I hung up before someone answered. Would like to let absa know that I have app**** to have my homeloan switched. As soon as this goes through, I will be closing all my accounts, including my bond account. I still have my 11 payments on my vehicle, also with absa, then you will not see me again. My wife and I have been with ABSA for more than 10 years. She also has a business account. There is a new issue every month. This was just the last straw.
