ATM solution gone Bad

towards the end of January I made a withdrawal an ATM, with fully fledged ABSA logos. The machine short changed me with ZAR100.00 I called Absa helpdesk, and was advised Absa does not deal with ATM solutions over the phone or online. I was advised to approach the branch. I managed that, but was advised to bring the receipt. I had to return to the branch the following weekend. I was then advised the ATM is not an Absa ATM, but is supported. I however have pictures of the ATM , and it boldly says ABSA. I now have received an sms that my claim has been declined. But I lost my money, and actually has declined my claim who can I contact to complain about the incorrect logo on the ATM, incorrect Branding
