Unwanted product

<p>In October 2015, I chose to cancel my Vodacom contract. Instead offered me a Wifi product. I informed them that I have wifi and I was told this can be used anywhere.</p> <p>The product is a wifi router which I do not need as I have ADSL line. I have not used the product and it is still in the original packaging.</p> <p>I have written to HelloPeter about this last year, however Vodacom has still not sorted this problem out.</p> <p>Now they are sending me warning letter for payments not made. </p> <p>I cannot pay for a product I did not want and was falsely advised by them to take it.</p> <p> </p> <p>I would like some advice on what I should do.</p>
