Upgrade done, no devices received!!!!!

About a week or so ago I posted a review about Vodacom (online /upgrade & cancellations department) regarding my upgrades and that I have not received my 2 devices as of yet. Still, even though they did respond the next day saying that someone will contact me, still failed to do so!! Does anyone have any advise to give me to get this sorted? Because I really don’t feel like going all the legal routes with this!
