Elite Mobile ****med me

An agent from Elite mobile called me and said my contract with vodacom is about to expire and I should upgrade my vodacom contract. She said my upgrade will include a MF 283+ ZTE router. I initially agreed. I later checked my contract and realized I had been **** to and my contract wasn't about to expire I was just being manipulated into an upgrade. I called elite mobile the very next day to cancel this upgrade. Then I was informed that I can't cancel because the router was on the way. I said how is that possible because the email I received said my order is still under review. How can it already be sent out. I insisted I do not want the upgrade. The agent said I will still be charged for the once off activation fee. I protested that I can't be charged for an activation fee for something I canceled. They refused to cancel the order or give me an email confirming the cancelation . They initial agent who sold me the upgrade said I could cancel the order within 7 days if I changed my mind. I am very angry at elite mobile, they ****med me.
