Unprofessional service

I am having a Business Account with ABSA, I wanted to cancel 2 of my other accounts with them for my EURo and USD accounts. They are refusing to cancel my account. I keep being sent from department to department, no one seems to know what is happening, I keep being asked for account numbers to be sent even though they have already been sent more than 3x. The details are on the email trail and they are just lazy to read back and check. Then someone comes back to tell me it's a wrong department , I must contact the other department, but their colleagues are the ones who sent my application that very same department.
