ABSA - ***** Department worst Service ever - actually NO SERVICE

I have tried unsuccessfully to get any reply from ABSA regarding ********** bank account details send to my clients. First reported 23 July 2018. Yesterday - 20 August 2018 - again a similar "change of banking details" send to another client of mine. Spoke to ABSA ***** line Vincent Maluleka and his response to my question why is ABSA not responding to my queries / emails was: - ABSA is under no obligation to respond / reply to my emails / queries since I DO NOT BANK with ABSA. Spoke / emailed also yesterday - 20 August 2018 to Paul Duncan - PA to the CEO. Also still no response. Please be aware of ABSA policy that if you are not a ABSA client they will not respond to any query / emails / correspondence.
