Which clown is running this??

Just some back story, In the middle of the year, 2019, I got retrenched from my job, as such I put in a request to cancel my services with WebAfrica, a few days later I got a call from a representative who informed me that this action would result in a huge bill and suggested we simply lower my package instead of cancel and take it from there, I happily agreed. Anyway, long story short, after 4 tickets to support to remind them that the package is not to be cancelled and simply changed and I could continue to pay (as per the advise of the representative), these 4 tickets have totally been ignored and I now owe them R4000.

I acknowledge it was my ignorance that lead me to cancel my services, but long before they were canceled I had already submitted 3 tickets to halt the cancellation and 1 ticket after the fact, again, all of which have been totally ignored.
