Cant get any support for a new laptop under warrantee - call centre does not answer, email does not work

This being my 7th Dell make my disappointment so much more. Since the day I got the laptop, service tag 58L45F2 I had problems. From hardware not working, to an extreme slow system. I ran all the diagnostics under the dell tool, all o.k. But take sometime 5-8 minutes to boot, 2-3 mintues to open a program, etc! I then went through the Dell website tool - first chose the Chat option on the South African Website - landed with a chat agent in Europe! Although she was very sympathetic she could do nothing since they only suppoer Europe. Gave me the steps (same which I had to a log a call). So tried avenue 2 - send support request - so now pops up this message to first run a diagnostic - after 15min a message from the browser that there was an issue with the application which determine on which Dell system I am on. Retried. Failed again. Ok, last option - call the call center. Followed the prompts, after 30 minutes listening to the same tune waiting for an agent I finally hang up.

Think I am going to return the product and ask for my money back (which I am really trying to avoid since I have setup all my settings etc already!) - Dell support which I used when living in Europe was so good...such a pity!
