Jet Store review: mobicel r6 2

I am having a similar issue with my Mobicel Vega at Jet Pavilion, seems this is a norm. In 3 weeks, my battery overheated and melted and swelled in my phone, I was refused a refund, phone repaired with an upgrade. Two months again my CPU is overheating, issues with major components again and I am so not happy. I am retrenched and am running up and down to solve these issues. I am going back to Jet Pavilion / mobicel to demand my refund as I refused to accept repairs on a clearly faulty phone. First time I have bought my mobicel, I will never buy this again ever. Only ten minutes on my phone im not using videos or watching a movie just simple apps and my cpu is overheating which is only happening recently, again another issue. The repairs claim that i will not be consulted about the repair cost, it will be performed without my knowledge. So this means i paid 1000 rands for the phone, paid for my screenguards two so far, petrol for running up and down and still pay for repair costs even thou im retrenched and this is clearly a horrible faulty phone? This is not fair and it is against our consumer rights. Never had so many issues with a phone before, i would rather buy a different reliable brand. If I do not get my refund when I am able to get to Pavilion Jet again for my refund, I will escalate this matter if I get no joy.
