ABSA not assisting in verifying and clearing payments

My daughter has a small business and have been working very hard to build and expand on it. The first few big transactions she received on sales done, were flagged as " suspicious payments". This is not a problem as that is part of the process. However, she followed up on this and was requested to submit certain documents which she promptly sent. Still nothing. She then escalated the issue and had to resubmit the documents which she again promptly did. The persons and companies that made the payments also contacted Absa to find out if they could assist in resolving the issue. Still the account remains frozen. In desparation she then made contact with the ABSA CEO's office. She was promised that the issue would be resolved within 3 to 4 days. That was two weeks ago. In total this issue have been dragging on for about 8 weeks and still no response from ABSA. Who else can a person contact as this issue is busy causing big harm to my daughters business as she has a nonexistent cash flow at this point. Maybe this is the way to close small businesses.........
