Bad customer service and damaged goods supp**** to

I have purchased a Samsung J1 in September 2015 and already I have a problem with this phone. The phone keeps on switching off all the time which is so frustrating for because I'm on the road all the time. I have purchased this phone from clicks in workshop in durban. I have sent the phone in for repairs and I have received the phone after a long time. Vodacom said that the battery is a problem but I am having the same problem again where the phone is switching off again. I am sick and tired of this now. According to the consumer act I would like to get a refund of my money back so I can purchase a phone else where.
