Poor Services

Hi, I'm so very dissapointed in the services I received from Tevo, I bought a Zingo in October 2015 at Mr Price Spor- Hemmingways in East London, Eastern Cape. I've been in contact with Farhaad as from the time I purchase the Zingo; within a month or two the Zingo was giving me problems and I was told to take it to the store where I bought it so it can be send away for assessment, it was send away and I haven't heard anything for months regarding the assessment, I contact Farhaad who said he will follow up and come back to me, I never received proper feedback so I informed Farhaad that I bought something else for my son and would like a refund because I've been waiting very long for feedback that I don't get, suddenly after a week or two after my request for the refund, the manager from Mr Price store phoned me and said that the Zingo is at the store and it has been repaired, I emailed Farhaad and asked him why did they repaired the Zingo without contacting me first because according the consumer protection act 55 together with 56 it clearly states that the customer has the right to request for a refund, repair or replace, my rights has been violated and I need a refund
