Still no Resolution

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. I did not receive any assistance after multiple calls, and after a review on Helo Peter, someone called from Vodacom and still after multiple calls, eventually the correct router was delivered, however I am still waiting for the mobile back up which was supposed to be sent immediately after the router was delivered. When calling back to query yet again, nobody has any knowledge of this and said that the special was over - however note that I app**** beginning of November. please can someone assist in resolving. 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.!!!
