The age old adage is "he with the biggest pile of paperwork wins".
So let's see what you've got.

Do you have the date, time, who you spoke to, and a reference number for that call?

Did it just jump in one go, or were there regular statements?
What is the additional R7000.00 for?
What have you done between when you first called to cancell and now to follow up?

It certainly would if you can show you completed the cancellation process, and it's an administrative error on their part, and you acted timeously when you discovered their administrative error...

It's quite a long Act. Could you be more specific by at least giving the section number, please.

Hopefully that gives you an idea of how prepared you are to fight this.

My advice - speak to their attorneys.
