@beka_valentine You got the result and they're complying now, yes?
If they've stopped doing the bad thing, the punishment worked, and now it's time to show them and others that if you do comply, then the punishment stops.
If you continue boycotting them after they've acceded, you've shown them and others that acceding accomplishes nothing, and they should simply ride out boycotts.
I can't help much with the icky taste in your mouth of doing business with a company you had to boycott, sorry.
