Sounds like inadequate preparation, the wrong paint or paint that wasn't fully cured.
Assuming that they are plastic emblems, use a paint formulated specifically for plastic. Sand any gloss thoroughly, clean with paint prep, then shoot with adhesion promoter shortly before the first coat of color. Apply light coats and allow the correct interval between coats as directed in the instructions. Heavy coats or inadequate time between coats will prevent the paint from curing properly. Allow to dry overnight (at least) before handling.
If the emblems are chrome plated metal, it is not likely that you will have good adhesion after painting over them.
