Hauwei P8 Faulty

I recently bought a Hauwei P8 which worked fine at first then wifi and bluetooth stopped working. Battery wont hold charge so they couldn't fix the phone and gave me another new one which has just done the same thing, both phones were not even 3 months old. This is a major inconvenience for me as the process of getting the phone repaired or replaced is about 3 weeks and I cant be without a phone for that long. I dont see why I must pay the price for faulty products, surely Hauwei is responsible for selling a problematic product. The Vodacom agent even admitted that they are experiencing massive problems with the Hauwei P8.
