ABSA Ignoring Loyal Clients

My Fatherin Law's bank account has been frozen due to some FICA issue. He is working in Zambia and cannot quickly go a branch so sort out the matter. We have been communicating with numerous ABSA Staff members without any resolution or feedback on the issue. We received a reference number (***7) from the Complaints Resolution Suite and I have followed up with that department and received promises of feedback but to date ABSA Staff has chosen to ignore a customer that has been with ABSA Bank for 30 years+ The account was frozen on Monday 15 November and the issue was immediately reported to the Kempton Park Branch where the account is kept and since then there was absolutely no progress and my Father is still stuck without access on his account. It would have been great if ABSA's Staff was held accountable for the loss of clients through BAD BAD NON-EXCISTANT service.
