Unauthorized upgrade on mobile wifi

<p>I was called by a sales consultant in January. The consultant advised that I am going to get a new mobile wifi which os faster without any extra charge. I received the device and the next month I was charged for it. I called them and they referred me to Mondo Vodacom to investigate the case. I was then called by Phindile Zondo on the 4th of April 2017 who advised that they did listen to the call and that I was misled. She also advised that they will be fetching the device and that the contract will be cancelled I will be refunded. Till today I've been paying for something I dont want and dont use. I called Mondo vodacom this morning and spoke to Melisha Ramlingam who was not helpful at all and ddnt give me any way forward. She says the outcome on the system reads that my investigation was invalid. So basically I've been taken for a run around and ****** day light. Ref 904</p>
