vodacom *****ing from the poor

Dear Peter<br> <br> I had cell phone contracts with Vodacom. I was owing around R9000 in 2014. When I defaulted, they handed over my account and said I should pay for the handsets and airtime and the total went to around R24000. I have been paying and I think am left with around R7000. What really ****** me off is that I am paying airtime that am not using since they blocked the sim cards long back. To me this is *** from the poor. How can I pay for airtime that I do not use??<br> <br> I would appreciate if I would get back all the airtime that I have paid for because I cannot pay for something that I don't use.<br> <br> regards<br> <br> Timothy
