I bought a new laptop Inspiron 15R on June 3rd 2013 and it came with a keyboard broken. I called technical support  and they asked me to send it for a repair.

I received it a week later  and after 2 days the touch screen had a problem. Technical support again made several tests and after an hour they asked me to send it for repair. It took 3 weeks before receiving the laptop. Between those 3 weeks,  I call back TECHNICAL SUPPORT AGAIN regarding the guaranty and they told me that they will give me another month of guaranty. When I received on July 22nd 2013, the laptop was not working. So I call to cancel this laptop  and ask for a refund because it is on guaranty. Today July 25th I am steel waiting for a call.
Dell lost a lot of quality.
