Lack of communication and customer centricity

ABSA's has frozen my business account now for the 3rd time due to FICA. Their lack of communication with their clients with regard to outstanding matters is concerning and downright lazy. The last instance after I have sent all documentation 2 months before and they not actioning it. Then there is one place on a form that I have not signed whilst my signature is in two places already on the same page that were not important enough for them to pick up the phone and discuss with me. Rather they opted just to freeze my account. The only way I realised was that I can no longer transact on my internet banking. SO I am stuck with no resolve other than to wait for them to process the single outstanding piece of paper. The frustration levels with this bank's lack of customer centricity is just next level.
