After nearly 40 years I am told my bank account is not FICA compliant

I received an SMS today purporting to come from the Standard bank ( ********** 422) telling me that my current account is not FICA compliant. I have, on many occasions shown the bank both my ID book and proof of residence. Now they want me to go to the bank again and repeat the process. I have been with standard bank for over 45 years in both Rhodesia and South Africa, I have just had an eye op and am having a further op on Monday. Right now I cannot drive and have no intention of wasting someone else's time asking for a lift. When I phoned to complain and asked to speak to someone senior I was left holding until I gave up. I cannot be responsible and waste my time and money as a pensioner to go and prove yet again who I am. I am not prepared to take responsibility for the incompetence and "couldn't give a damn" attitude that this bank takes towards its customers and after 45 years + I am now going to look for an alternative.
