no collection of incorrectly supp**** goods

Cell c called with a promotional item that was a wifi router and data. I agreed and waited seven working days for delivery (27/11/15). When opening the package a ****le was sent not wifi router. I called cell c customer care and explained the situation and said it will take seven working days to collect another seven working days to process the incorrect sending of item and than another seven working days to process the correct order. So 21 working days to fix there mistake???? <br> Until today I am promised everyday that it will be collected and still nothing. I have called numerous times spoken to a manager and which he promised to call back and nothing. I called three times last week and even today and i am told the same thing everyday that it is not there fault the couriers have not come yet. I am told i am not allowed to drop off at a cell c store but will be charged until they can see the device has not been used! Unacceptable service it remains cell c job to collect and ensure service!
