Absa no client service at all ever in any way

I can not express what a horrific experience as a absa client was from young till now it. Has never ever been pleasant. I have sent several emails to them to fund missing payment to my credit card. And also to help with correct payment. I have never been helped. It's been months. I get a call this morning from a lady saying she's from absa and demands my ID number in connection with my credit card. I ask her what will she fix cause I need to confirm she is from abs and she drops the phon e. I have called and went to the bank. No assistance from absa.
