Unacceptable Customer service at absa bank

It has now been 2 days that I have to repeat the same question to ABSA Agents. To get such bad service which leads to no proper answers and zero outcome for assistance is appalling. I have requested to have a card removed and to add my new card onto the Telephone banking system in order to make a payment from my Private Banking card. To no avail. Some agents take the call and absolutely before you can talk the phone is put down in your ear. Some instances the call is put through to an agent not speaking to me and the call is ended. It is absolutely rude telephone etiquette for treating a Customer. It seems ABSA is employing a vast number of individuals to meet numbers without properly Training them on how to deal with a Customer. I cannot wait selling my property by end next year to close all accounts with this banking entity. I have had bad experiences with absa this past year. I even attempted to have my request fixed within a branch but to no avail.
