Billed for router that doesn’t work

<p>On the 27th of April I upgraded my contract with Vodacom Trade Route Mall. I set the router up however it was faulty. I returned the router to the branch however I am being billed for something that is not working. I would also like clarity on the amount of R1696.95 billed. Can someone from Vodacom call me to explain. Best time to call is in the morning. </p> <p> </p> <p>Rehana</p>
