Incorrect goods & still no replacement 1mnth later

I did an upgrade through Vodacom direct sometime at the end of August.<br> I requested the Vodacom mini wifi ****le and it included a free 1 TB external harddrive. <br> <br> On the 31st August the courier delivered a larger home router and no Harddrive.<br> Since then i have called their call centre numerous times and still not received the correct goods. <br> I have called every few days and keep getting reference numbers for a collection and reversal of my upgrade but still no one has collected the incorrect item. Many time the phone just puts me on hold for more than 15 minutes.<br> <br> This is ridiculous, more than a month has passed.
