Telkom please clear my name!

I need a letter confirming that I have paid up my Telkom account. The service centre at Galleria mall can see this on their system but they say they can't print it out. Their back office that deals with this does not take calls and is not responding to email. The initial request for this clearance letter was submitted on the 28th of February . Today is the 13th of March but no such luck.

It seems Telkom is determined to keep me in their bad books. They refuse to log a call to assist them to at least print out my statement as proof of my payment
