Offered a wi-fi router at NO COST

I was offered a wi-fi router, as an existing Platinum client of FNB. The official called me and said I can have the router at no cost (for free) and nothing will change, that my current contract will remain unchanged. I have an existing data bundle package of R99 per month for 24 months which expires in March 2016. To my utter dismay, my bank account was debited with R191.61 on the 21 Nov 2015. I spoke to a lady at FNB Connect who works with the contracts tel nr ***, who had to revert back to me but was told she must first listen to the tapes. I told her that I expect my money to be refunded as I never agreed to a pro-rated package and was misled by the consultant who offered me the free router, as a loyal FNB client. I am still waiting (2 days now) for feedback. I am extremely unhappy with the services of FNB devices and will think twice before buying any devices or data bundles again. I would like my money to be refunded and this matter resolved immediately. The \free"router is not free. """
