False advertising and Poor Service

I app**** for Vodacom Fibre around the 3rd of November, I app**** for the promotion which was for the Uncapped Fibre and a free S90 router LTE auto-switch, and stronger Wi-Fi coverage, plus 40GB mobile backup data for always-on connectivity which was and still is advertised on the Vodacom website. I confirmed telephonically with the agent that called me to confirm the order as well. Before the technicians came out, I called to advise that RAM was not in contact with the router delivery as yet and I was told that the technicians will bring one. The technicians came to do the installation and delivered a router and there was no mobile back up as per the order. When I queried it again, I was told that it was not on the order, yet I did apply for this promotion. Upon querying several times, they agreed to order one , however it was noted that I was given the incorrect router which was a S3 and not the S90 as app**** for. Up to this day I am still awaiting some sort of assistance in rectifying the situation. I have to call Vodacom everyday and still no resolution.!!!
