Vodacom sucks

I was called by a sales agent a few days ago who said that because I was a loyal Vodacom customer that has been with them for a few years they would send me a free LTE router. I asked her a few times if this would cost anything extra and she said no. Then at the end of the call she says she just needs me to confirm that I agree to a 24 month contract, I asked why I needed to have a contract if they just want to send me a router, only after I'd asked her this same question twice did she admit that she was trying to get me to sign up for a 24 month LTE contract. This call was extremely ********* and I am not happy that this person tried to trick me into an additional contract which I do not need.
