ABSA - Not interest in listening to their clients

My company opened a Business account with ABSA (Al**** Bank in those days), as an Estate Agency we require a Trust Account. We have had these accounts for many years. For some reason and WITHOUT discussing or communicating with my company ABSA decided to change the names of my Bank accounts in 2016. This only became evident when requesting a Tax Certificate for our annual 2017 Estate Agency Affairs Board Audit in 2017. Upon querying this with ABSA I was told that this is how it is. Goodman Ngubeni the Sales Manager Small and Medium Business Eastgate has decided ABSA do not have any profile created for my trust account, despite me providing proof of the trust account cheque book which I have in my possession issued by ABSA Bank in the name of the company Trust account. and all the previous year's bank statements and tax certificates have been issued by ABSA in the name of the company Trust account. Mr Ngubeni has advised that despite ABSA providing the relevant tax information on my Trust account for more than 23 years, ABSA after changing my banking profile without discussing or notifying me will be unable to provide a the tax certificate in the name of our banking Trust account as it will be in violation of ABSA bank's integrity because ABSA will be unable to prove that account number I have had for 20+ years is a trust account. I am gobsmacked that after 20 odd years my business is now at risk because we are not able to supply the required information for our annual audit, which is automated. Instead of trying to meet my requirements as a client Goodman Ngubeni from ABSA Eastgate tells me that they cannot prove I have a trust account, and shows absolutely NO interest in listening to my needs, instead insists of telling me that ABSA cannot trace my Trust account and I must ABSA how ABSA has changed my banking profile WITHOUT my input or the courtesy of discussing it with my.
