This does sound indeed like an unusual issue. We will be more than glad to assist you with this situation.
We will however need some more information from your end.
Have you checked to see whether it is the adapter (it screws and unscrews) that has stayed in the socket ? Or has the base of the bulb (the one with the smaller connector) fallen out ?
Please send us your name, a number which you could be reached with, and pictures of the bulbs and the fallen sockets to email@example.com and we will assist you with a personalized follow-up swiftly.
