New 3DS XL Dual Screen Swap

Hello everyone! Hope you're all doing well.

I recently purchased a New Nintendo 3DS XL Pikachu Edition, which came with dual TN displays. I then proceeded to buy a top and a bottom ips screens from eBay sellers that this individual recommends in his YouTube video (https://www.yout.ube.com/watch?v=JM980v7V66s).

I then took my New 3DS to a local shop and asked one of the guys if they could do the dual swap. I explained to him that even though both screens are in perfect working condition, I wanted them taken out, and the IPS that I brought them to be placed in their instead. He complied, gave me a quote of US$70.oo for the labor, and estimated that it would take a couple of days.

That was last Monday, Sept 25. On Friday, Sept. 29 one of the dudes from the store calls me at around 1pm, and asks me why I wanted to replace the top screen, since it was in perfect working condition. Mind you, this was a FULL FOUR DAYS that had gone by without them working on it. I then proceed to explain to him the same thing I had told his colleague, and how IPS looks much better, etc. He then says that there's no way to remove a certain cable from the top screen, without completely breaking it. I had told him that I needed the working parts that they take out, to be able to resell them on eBay, but after hearing that, I told him that it was okay, that he could break the cable, as long as the IPS screen that I had brought him was placed without any issues in the console, everything would be fine. At this point, I am questioning the dude's expertise in the matter, since I had seen a YouTube video of a woman replacing the top screen without damaging it whatsoever (https://www.yout.ube.com/watch?v=8ZGrG-GAPsA), but since it's almost been a week, and I just wanted my console, I didn't care and just told him to finish the job.

I called on Saturday, Sept. 30 at around 12pm (almost a whole day later) and the same dude picks up the phone. I ask about my New 3ds XL and he, kinda rudely, says that it's not done, and that they will call me when it's ready.

It's Monday already, it's been a whole week since I gave them the perfectly working device with all the parts (top and bottom IPS screens) to be replaced, and I still haven't heard from them.

I know the shop specializes in phone repairs and the such, but their website also mentioned console repairs and that's why I went with them. What should I do at this point? Keep waiting? I have the impression that the dude messed up something while trying to swap the screens, and now they had to order a replacement part for it.
