I’ve tried boiling water but that didn’t work
Pour a safe solvent that is not petroleum based, such as Un-Du Wax Remover, down the sink and wait for it to unclog.
Here is an answer:
Hi Cameron, Boil water and pour it down the sink. It may take some time for the water to drain completely. Repeat as often as necessary to make sure the pipes are flushed of the wax. You can also run hot tap water to flush the pipes as the clog begins to melt.
You can get a snake for the drain. Manual ones aren't very expensive. You just work it slowly down and back it out. Check Harbor Freight.
Pour boiling water down the drain. Repeat until the drain is clear.
Hi! I would snake it to keep it from moving further down your line and then follow up with hot soapy water. Good luck and stay safe!

Hi Cameron: Give this a go: Heat water in a teapot to boiling and pour it down the sink. Immediately pour in a 1/2 cup of baking soda followed by a 1/2 cup of white vinegar. Cover the drain with a plug and let the solution work for an hour. Flush again with a teapot full of boiling water. Or, go to this site for a bit more help:
I found these ideas for you
Cameron said in his question that he has already tried boiling water.
Look under the sink, Turn off the water! Unscrew the "U" bend and clear that out. Should sort you out!
You need to run the waTer longer very hot water run for like 15 min
