Keloid on tragus

I got my tragus pierced the beginning of January, and I developed a keloid scar about 2 months after. I called the place I got it pierced at and they told me to apply some solution that they sell there for 3 weeks.. I followed all their directions and it’s still there! I went back 3-4 weeks after like they said and he told me to keep trying the solution, and that it takes 3-4 months to fully heal.. well it’s been almost 4 months and it’s still not gone! And it’s so much bigger now! 😔😣😭

What should I do? I don’t wanna go back to them. I also really don’t wanna take out the earring:(
