Absa Bank - possible reckless lending

Absa services are shocking!!! I sent them an email on 23 September 2019 with a query on possible reckless lending! I have resubmitted that same email to them as I had no response, and gave them until 11 October 2019 to send me either a reference number or an acknowledgment to my email. I have not received anything from them. They are completely ignoring my emails and requests. I warned them that if I do not get a response, I will take matters further!! Absa please kindly respond to my email and investigate the matter at hand before I take this even further.
