I bought a high end pc monitor through amazon which turned out to be faulty. I requested a replacement within the 28 day guarantee diect from Asus which I got however realised after a day of use that is was second hand. Again has to call them for a replacement to a new one like i paid for, they refused to do so, The customer service agent was extremely rude and condescending. She consistantly tried to talk over me and refused to get me a manager to speak to. Im am just so glad I contacted amazon who took away the second hand replacement and gave me a brand new one like owed. So thanks so much to them.
