Unfortunately we can not accept the return if the package is opened. If you have tried everything and still have fleas you must have flea eggs in your house. The best way to deal with it is to spray the whole house and vacuum clean thoroughly to get rid of dead eggs. Make sure you wash your dogs beddings too. If you use the flea collar at the same time you should be able to get rid of them in a few days. We actually had the same issue and completely resolved after doing the things above.
