No delivery of goods

It is 5 Months after i was suppose to get my TV and Kindle (which i am paying for every month) Now suddenly they cant supply me with this anymore but i still have to pay???? How does this work????? I have spoken to so many people in Telkom and no one can help me. I have laid complaints on different sites including this one a few times and nothing happened... I am now laying complaint at the consumer Act because clearly nothing else is working. The people i was dealing with is now not even answering my e-mails anymore and i do get read resets so they do read it, just don't replay. Consumer Act is all i can think of as my next step as i have tried everything else.
