Absolute incompetence from ABSA continued

I wrote a review on Hello Peter regarding their inability to provide me as executor of an estate with the required IT3 tax certificates. Despite having sent two complaints to the ABSA action line I have had no response from them. The Absa website states the following: Should the complaint not be resolved immediately, Absa will register your complaint and provide you with a reference number. Within three (3) business days, you will be provided with a resolution or the estimated time required to resolve the complaint. In the unlikely event we cannot resolve your complaint within 20 business days, you will receive a letter of resolution/conclusion on our position or an indication of when we expect to reach resolution. If you are not satisfied with the resolution/conclusion, you are invited to escalate your complaint as indicted in the escalation process. None of this has materialised and even the review on Hello Peter has after 5 business days not elicited a response. It would appear that the following step would be to involve banking ombudsman.
