ABSA customer service

I had a dispute on 2 accounts on outstanding balances. You can try as you like to get hold of customer services and if you're lucky enough to reach them, they will inform you to send a mail with your query to a specific email address and that someone will action within 14 business days. Eventually you will get a reply and if you don't agree with the reply you have to send another mail and wait another 14 days. I have sent a mail to the department manager as well, still with no reply. All of the sudden you will recieve an email stating that your query was resolved and that the ticket is closed. This has been going on for a month and a half already without a resolution.
