Zif connector found to be glued from factory after 2 years

I recently upgraded my MacBook Pro 13" Retina display (early 2015) hard drive to 480 gigs, which was done by a friend who has replaced 3 of his apple hard drives with no issues. After installation the keyboard would not work. He did not know a lot about the inner workings of things related to the keyboard so we took it to a local Apple technician. (Keep in mind, I was with my friend the whole time and at NO time did he go anywhere near the keyboard area, which is on the opposite side of the computer) When the Apple tech looked at the ribbon that connects to the keyboard, he saw that the zif lock was missing and also the flap that covers it when the laptop is sealed. Here is the kicker, the connector itself was GLUED in place at some point and obviously was never connected using the zif lock. Here is what I have:

Here is what the ribbon and connector are supposed to look like:

When comparing the two pictures, notice there is no flap on the one I have and the zif lock is also missing. There is glue residue on the top of the connection area and you may not be able to tell but there is glue on the area that is under where the connector sits.

The tech says that if I never had it opened before, (which I have not) then it must have been sent this way from the factory and when we opened the back to replace the hard drive and released pressure on it, it popped off. He said it wasn't even in the slot when he opened it and the glue was so thick he could not get the ribbon connector in the slot without removing some of it. I notified Apple, but of course, they say it's out of warranty and can't do anything.

I am trying to see if anyone else has had this issue. I feel this is factory fraud! It was sent to me defective and without all its partsfrom Apple. My question is has anyone else had this issue?
