Bad customer support with \next day"warranty"""

3 Nov-contacted Dell to come and fix my laptop (3 year, on-site, next-day warranty). Cd drive was not ejecting, laptop was crashing if touched underneath. <br> 4 Nov-told that tech would come 5 Nov<br> 5 Nov-told tech would come 6 Nov as parts not avail. I postponed as would be away for 2 wks. Laptop working perfectly aside from the issues mentioned.<br> <br> Mon 23 Nov I ask for tech to come next day. <br> Tues 24 Nov tech came at 12:00 replaced parts and left. After a bit I noticed that the fan running very loudly and does not switch off. I report the issue. While on the call the battery starts running flat so I plug in power cable and noticed it is not being recognised. Laptop runs flat and switches off. (Tues afternoon). Am promised that tech would come on Wed.<br> Wed 25 Nov am told parts not avail.<br> Thurs 26 Nov heard nothing. <br> Fri 27 Nov (after not being able to turn on laptop for 2.5 days) am told tech will come in pm.<br> Tech finally arrived at 6:30pm! (Why was I not a priority?) Tech replaces parts. Laptop appeared to be working. A few hrs later, I notice audio no longer works! <br> Have had 7 parts replaced in a week. Laptop still broken. I would like to escalate the matter and request a new machine
