Glad you bought there - they have both an amazing selection and quality of plants! I'd be in so much more trouble if they were around the corner from me!
Post a photo of your Phal if you have one. They could be calling a violacea - bellina and violacea are often mistaken for each other. A pic of the flower and the plant up close would help ID it!
Don't forget that fragrance is a means to attract a pollinator. It's often time dependent: that is, it will turn on and shut off at different times during the day or night, depending on what critter is meant to pollinate the flower. At night it could be a bat or moth; during the day it could be a butterfly, a fly, a bee, a...whatever!
