the paper towel method has a really high success rate, usually also exhale into the bag to supply some co2, and leave it on top of a cable box wrapped in a black sock(if your box is in direct light you might want to use 2 layers, they really need darkness). usually takes 2-3 days, then breaks the soil in 1-2, dont plant it far down, id put it a very small layer of dirt over it and keep it pretty damp.
also handle the seeds with care, those roots are fragile. check on them every day so they dont root into the towel, and keep it damp.
those seed may have not been viable, email the site you ordered from and tell them they didnt germ.
