ABSA bank *******

I have been contacted by absa to raise the limit of my credit card. The next day R15000 went out of my credit card account. The bank I went to confirmed that it was internal ***** as the ****mers phoned me while I was in the bank. Meanwhile I am left to pay the interest of money ****** by ABSA themselves!!!. My ***** claim has been declined after mountains of proof. What is happening inside ABSA? DO NOT BANK AT ABSA THEY ARE *******.
