Incompetence, *********, No Customer Service, and the list can go on and on

So I decided to get one of MTN's uncapped data deals in Dec 21 through their online site. After receiving the item and struggling to set it up, even after calling them, I manged to find instructions through an outside website. Nevertheless, after a week I received another of the same package without applying for it. I returned the router and sim to MTN Tyger Valley Jan 22. Till Aug 22 I was struggling to remove the package from my account. In Aug 22 I was informed that it was removed, but now in Sep 22 I see that it wasn't and my account increased by R1300. What the hell? This is completely unacceptable.
