Contract ended, Telkom still charging me!

Hi.

I have a chose Telkom to get my devices from. I have 5 devices from them. 3 of which ended. 1 particular device, Sony Xperia Z5, ended in June 2017, I bought it in June 2014. Telkom has been billing me for this device every month since then. I received my latest invoice for August and they are including the cost of the Xperia Z5 there too, they are also charging me for the Z5 in September! What bull****. if I did not pick it up, they would continue to charge me R400 for the device every month going forward. Stop *****ing! I want my money back and I want a compensation plan for my troubles. That's money I could have used for food every month! Ridiculous. I logged a case and I am still waiting for them to call me back! Here is my case number ********** 0.
