Poorest service ever

This is not a first time. Whenever I request documents or give a form to be filled in they are always unable to help. They give excuses after excuses but the moment I start to fight with them for not helping I asked the numbers to be phoned for help and phoned right there from my cellphone in front of the teller and only get attended to by the person on the phone. But the teller in the bank is unable to help. Why does this always happen. But when you go to other banks you get service immediately. I'm taking my business away from Absa bank.
