Query: BAD AFTER SALES SERVICE

I bought the AL2021MS in March 2006 and in November 2006 it started to malfunction (kept turning itself off). I called Acer support as it was still on Guarantee and was told they would replace it in 2 days. 3 days later I called them again and was abused by their help desk, told I had got it all wrong and that it would take 2-3 weeks. I am still waiting for a replacement screen. Apparently they are out of stock if it breaks under guarantee but will sell you a new one as they have enough stock to make a sale!How did I write this review: I am using my old 1999 15inch DELL monitor that still works.IF YOU WANT REALLY BAD AFTER SALES SERVICE AND A LCD SCREEN THAT ONLY WORKS FOR 6 MONTHS BUY ACER!!!!!
