Up right Vacuum broken after less then 3 months

My mother bought a vacuum from Game in December 2015, and in beginning of March 2016 the unit stopped working. I took it back on her behalf to request a refund on the 8th of March. The store called the sales person for the Tevo brands and she insisted that we can only have the unit repaired, I explained to her that the CPA states I can choice if I want it repaired or not, and I didn't I wanted a refund or a new one. as the repaired unit will not receive a new warranty it continues from the date of originally purchased. she insisted that I don't know the CPA and she does, and therefore I can not have a refund, only a repair. I even looked up the CPA on my cell phone to show her but she was not interested. she contacted her manager via a landline and we spoke to him as well, and the same thing he insisted a repair and we cant have a refund, it was a take it or lose it situation. I do not want a repaired unit I want a new unit or a refund and I will buy one somewhere else. the service from Tevo was horrible, the sales lady was more on whats app then assisting us with this issue. And we have still not received any feedback from Game or Tevo!!!!!!
