Defective product and poor support

<p>Bought a Nextbook tablet from Makro. After using it for a while the device refused to turn on. I took it in and after a few weeks received a working device. Now after a while of receiving the replacement I seem to have the same issue. I have brought this issue up with the twitter handle as well as with a direct email and I keep get people asking me for details but nothing is being done. Due to the issue clearly being a design fault all I want is a refund so I can purchase something that works</p>
