Standard Bank does not give feedback or take complaints seriously

I am referring to my previous complaint regarding no communication on a loan account that is apparently outstanding, that I have not heard of since 2017. Even after complaining on Hello Peter and numerous emails, I still get no response, just some vague replies of 'we are attending to this matter with urgency'. This is the highest rate of worst experience ever! Standard Bank does not get back to you, even when complaining and contacting on numerous occasions. Please sort this out or I will be forced to take this matter further.
