Pathetic service and store policy

I bought a PS4@ Pick n Pay Ottery for my son on the 02/12/2018 .The PlayStation started giving a problem and could not switch on after 2 weeks of usage.Pick n Pay Ottery and their manager refused to exchange or refund the PlayStation.We were told we must contact PS4 and arrange on our own to get it fixed.Long story short.Pick n Pay has an exchange and refund policy of 30 days but we were told that unfortunately it does not apply to PS4... totally upset and revolted with lack of service at Pick n Pay Hyper...spent so much money at the shop and told be thrown with the bucket full of nothing...
