How to keep the customer unsatisfied even after spending 6000 times more than required for him

As expected from a year old laptop, mine had also started to shake on the table when in use (literally). I had lost a bush (KD did it, I take care of my lappy like a mother of her baby) which was located under the battery of my XPS. Being an industrial Engineer, I was forced to apply the Quality Norms (Basically, Just in Time) and ended up logging a complaint on Feb first week (My warranty expires on March 5^th) for this issue. First we had a small chat on the missing bush, then on the underperformance of the battery (5 hr. backup to 1 hr. in 3 months.. That’s Dell.. Everything is preplanned) and keyboard issues (nothing.. my keyboard simply rocks) etc. etc. and at last we stumbled on the flickering issue (Blurred display when I run on battery). We had a long chat (24 calls with average duration 4 minutes) on this issue basically coz he was more into troubleshooting than into replacing my bush (damn him)

So we carried on with the different troubleshoots (It was very much easy to manipulate considering that am a Linux user :D) and finally he decided that he is going to replace my motherboard as well as my LED display. He was continuously taking decisions on my laptop and I was waiting so that I can take up the "bush-issue" again but he never gave the chance. So finally when he was finished informing me how much screwed up my system is and what a rough user I was, I took up the bush–issue again and this time his observation/analysis/solution was way too quick.

• Dell doesn’t replace just the bush. They have to replace the battery if they want to replace the bush.
• As my battery is performing way beyond the expected level (according to him, dell 9 cell batteries are not supposed to give a backup of more than 30 minutes after 6 months and if its giving, it’s a flaw with the batter and not the other way around), they cannot replace the battery for me even if my laptop is shaking when in use.
• As battery cannot be replaced, we have no choice but to remove the other bush and make it aligned or attach some cotton under the back, so that laptop rests on place

So finally, after this week long discussion to replace a 5 rupee bush for a comfortable use, they are replacing parts worth more than 30K for free and still leaving me (customer) unsatisfied.

Btw, Dell Rockz!! Or to be precise, if any laptop actually rockz, its Dell!!
