Galaxy z3 screen protector bubble coming off

[NH GAL]

My z3 flip has a problem with the screen film that is develop8a bubble. I found thru this site I could get it replaced. I made an appointment at the authorized repair place(Best Buy) When I showed up this AM I was told they didn't have the replacement part and I was the 2nd person this morning looking for this fix. I am really disappointed.  I like my phone and my Galaxy 5 was great it lasted 7 years. What should I do now? Can Samsung mail me the new screen protector and I can take it to Best Buy? I know it must be replaced by a certified technician.

You are probably best asking on the U.S community for a more regional answer

I don't think they will mail it to you and I'm not sure if it's available to purchase where you are.

I know it can be replaced but I'm not sure the level of care you'd need to do it.
That's why it's advised to get an authorised repair done
