Urgent complaint which Capitec does not give interest to

On Dec 6, 2019, I emailed Capitec's clientcare to address a complaint I have with what the branch did, on their website they make it known, "Unresolved complaints will be escalated to Complaint Management.

We will acknowledge receipt of your complaint escalation and give you the contact details of the person investigating it We will make contact with you within 24 hours and keep you informed until your complaint has been resolved Should you not be satisfied, we will provide you with the relevant ombudsman’s contact details"

So here was my email I sent them - "Good day, to whom this may concern,

As far as I am aware are you not allowed to give my personal details out to any other customer asking!

I want to speak to a higher person in charge that can trace who told that person my details, there is a customer's confidentiality that you just overstepped or someone in your Capitec branch and I hope that person is to be found and dismissed.

Please let me know ASAP!"

I have emailed them again Tuesday 10 Dec 2019 to follow up and still, no one has come in contact with me. I have not heard anything from Capitec and it is Tuesday 10 Dec 2019 11H45PM I do think this is a matter of urgency as who gives that person the right to give out my details to another customer.
