M1530: Did Dell F up my repair?

I have an XPS M1530. (skip story if you want, important stuff bold)

Dell sent out a guy to repair my speaker and ended up benting the metal under the keyboard and not reconnecting the finger print scanner... sent out another guy to fix that, broke more things... and finally sent another person with wrong parts before just asking me to send it in.

I did. It came back like new. Until 4 months later the touch music bar/speaker cover (is there a name for that) stopped working. I opened it up and found that the cable slipped out and was only connected by TAPE. is this right?

(I emailed the guy(ramjee) who helped with my repairs and he sent me a driver link)

(I called dell and explained that it's a connection problem and she just repeated: "Sorry out of warranty and we checked up on you 4 months ago and you said everything has been resolved")

(I took pictures and sent another email to Ramjee and he is now helping me again. I believe first sending a new touch/speakercover thing.)

I need pictures or even written confirmation that the clips are missing and if tape holds it on:

Mine looks like this:

 

To me the left cable (blue and white) seems loosen. Pull up those two little black guys next to the cable, insert the cable back and push the black guys may solve it...

By the way, if I were you, I would just ask them for parts then do it myself...

 

the cable on the left works fine. I am wondering if the one on the right should also have the plastic locking tabs like the left has.

They are sending me the parts. But I think it's the motherboard connector (right one) with the issue.
