Worse experience on a prescribed account

I have been having the worst experience from the customer service department and been sending numerous emails which days pass with no one coming back to me. Last consultant I was chatting to via Facebook Messenger with the initials Z.N has blatantly ignored my escalation that the account of 3 years has been closed and prescribed. I have even sent all the proof stating such but now Z.N has ghosted me refusing to inform me if she will be escalating my query or not. Does it really take more then 10 days for Tshepiso in the legal department to respond to emails, like what must one do to receive assistance in this company!!!!!!!!!

The worst part these consultants do not even educate the clients on prescription and when you raise it, they ask you irrational question as if a client/account holder is not allowed to raise prescription on an old account.
