Mobile contract redundant terms and conditions when it comes to pricing on early cancellation

These cellphone stores are really a joke when it comes to contracts and the ways in which everything within that loin is structured. I called in asking to make an early contract cancelation in an attempt to take a new phone. I had already paid for my current phone for a year already and this is a 24months contract. They charged me R8700 for an early cancelation and I am paying R400 per month.

Now when I Calculate the amount that I will pay for the remaining months if I pay as agreed it amounts to R4800. Maybe it's myself who is concerned about how this is structured especially when I'm going to come to the same place for business.

I had the same issue with Vodacom regarding my Router, not even a router it was a sim card deal really because that that point I had paid off the router they were just providing the data and for cancellation for a better offer they charged R5800 and with that amount of money i wasn't gonna get any data whatsoever for a deal that i was only paying R200 for. This really is redundant and unnecessary for customers who are willing to stick with the some company to be treated like this.
