The most unreliable brand

I bought a Asus Zenbook UX302LG on 24 June 2015. On 5 October 2015 the unit failed to boot and the HDD made a noise. I sent the unit to the authorized service agent, Ensure IT for repair. They replaced the HDD and SDD. This took 3 weeks. On 27 February 2016 the unit again failed to boot and made the same noise. I again sent the unit for repair. The HDD and SDD was once again replaced. I requested Ensure IT to check the unit further as it was quite obvious that the HDD was only a symptom of a bigger problem - probably a power surge caused by the MB. Ensure IT was non-responsive and unhelpful. I contacted the ASUS call centre. The agent told me that the Ensure IT's decision is final and that the unit will be replaced if it fails for a third time. When I received the unit back after 3 weeks the unit took more than 25 minutes to boot to Windows. On the second boot the OS displayed a blue screen error - "Device Power Driver Error". On 12 April I returned the unit to the agent as it was impossible to use. This was the third time it was sent for repair. The technician at first gave me the feedback that the unit is fine as it boots to Windows. After various emails they tested the unit and found that the brand new HDD and SDD are faulty. I contacted ASUS customer service via their website. They responded by saying that only after the third repair a unit may be replaced. After various contact with the agent they said that they found the MB defective and will replace it. Thus all the electronic components of the laptop are replaced. This is quite unacceptable for a high-end laptop. I definitely made the wrong brand choice. I will never again buy ASUS for myself or business and will not recommend ASUS to anyone. Their call centre agents are rude and unhelpful. Their authorized service agents are unresponsive, ignores the real issues and unhelpful. I will rather now write-off the money I spent on the ASUS as a bad choice and buy a new laptop than risk losing my data again and being without a laptop for the fourth time in under a year. ASUS - the most unreliable brand!
