Terrible customer service, still waiting for a response/call 45 days later

I have contacted Absa with a query on 24 April 2023. Have spoken to more than 30 people in their call centre, receiving no response or the decency for the Team Lead or Manager to call me back. I've sent many emails as well with only 2 responses stating the consultant is awaiting a response from their Manager. The Manager has not contacted me or made any attempt to even seem like she cares about Customer service at Absa. It has now been 45 days of me trying to get an outcome to my query, making multiple calls at my own expense. I'm quite frustrated as a client, and don't think I would recommend anyone to Absa with this kind of customer service or lack thereof.
