The Worst Business Banking Service Provider

I am deeply disappointed at the lack of customer care from ABSA Business banking. No concern for customer service whatsoever. I supp**** the necessary compliance documents required to keep my account active and in good standing 3 weeks ago and was assured by my business "banker" that everything is in order. Today i try to do critical payments the account gives a FICA error. i call the banker who miraculously answers and she is adamant that FICA is compliant. i beg for her to check the account and give me feedback to which she promises that she will do so immediately.. i wait for 1.5hours - nothing, i call 4 times, calls are rejected. i call the call centre as a last resort and they say the account is not FICA compliant and i should contact my banker. i try again - no response. I escalate to her manager - No response. What level of poor customer service is this?????? Pathetic
