Misleading information on Conexis X2

In December 2018 I went to FNB in bridge city to get a Conexis X2 as I was on reward level 5 and was told the phone would be free as long as I meet the requirements. I have met all criteria and have not been given my rebate. When I phoned FNB connect to query they transferred me to eBucks as they said eBucks would help me. I spoke to Ismail Mohammed and he told me rebates queries are handled with FNB connect. When I was transferred to FNB connect I was told the operating hours are Monday to Friday. I am highly dissapointed as I was told the device would be free if i am on reward level 5 and meet criteria. I have met the requirements. Had I known I would be charged monthly I would have never taken the device as it was not worth the price. If I am not able to get my monthly rebate then I want this contract cancelled
