GUYS I HAVE IMPORTANT NEWS: I GOT FREE REPAIR
be prepared for what i am going to say, it will be unpleasant for most of you but i hope to let you get my impression and what i feel like it worked in order to get a free repair.
I write from Italy, Milan and my problem regards a MacBook Pro 2017 13'' (2 thunderbolts, no touch bar) since september 2020, i tried a lot of calls to Apple support, at least two different practices with long trials via software updates, computer formatting and many other useless solutions: the problem was definitely hardware.
I think that someone in this discussion got the keypoint: it seems a detail but i seriously think that what makes really the difference in this terrible situation is the Keyboard Service Program (https://support.apple.com/keyboard-service-program-for-mac-notebooks), i don't know why but i had a feeling that there was a correlation between this program and the other one (yes you read it correctly: THERE IS ANOTHER PROGRAM).
Yesterday, unfortunately, or now i would say fortunately, one key fell off, i also noticed the barspace having some issues when writing (sometimes double space was written with one touch) and in my mind i remember also the bottom arrow being sticky.
Without any hope i went to Apple Support and also tried again to talk about the horizontal lines problem: they recognized in 5 minutes the keyboard problem, and BE PREPARED... they also recognized the horizontal lines, they even didn't want to see it, a picture was enough for them (and by the way is the same pic you can find above this answer and that other apple workers refused) mentioning that there is "another repair program", i literally asked for the name of it and where to find it, the worker smiled and told me that "some of these programs are silent", can you imagine guys? SOME OF THESE PROGRAMS ARE SILENT. I had spent lot of time asking about this problem and the answer was always the same: there is no repair program for this.
I don't know if those of you that received this response went phisically to genius bar, i feel like this is an internal procedure that they apply in certain situations (and here i think that they apply it mostly if you have also keyboard problem), but if no information is provided on their website (like with the first repair program) maybe online they will tell you that it doesn't exist simply because they don't know it and they read the info from the website.
At the end of the day they recognized both problems and give a free repair for a total amount of almost 1000 euros, this can't be real.
I will add an extra point: to me the worker was a lot aware of the problem of horizontal lines, in 2 seconds he said that he knew well that problem and that was related to "some connectors" that had this issue and which is causing in these models sometimes horizontal, sometimes vertical lines, to me it looks that he literally said that apple knows well this problem, this strategy seems a sneaky way to minimize free repairs. YOU MUST INSIST GUYS.
I don't know, i am seriously confused, happy for me but sad for you, i want you all to insist as i did, trying the approach i pointed in this answer. The following pics proof what i am saying.
