Hi Lilacjc, welcome back to the community! Thank you for posting.
Sorry to hear about the mysterious empty envelope - I can appreciate this may be a concern!
We wouldn't be able to confirm if this was the phone adapter you are awaiting without checking the account, so I will need to send you a PM and confirm a few account details. You can find the PM in the top right hand corner of the page in your Inbox. Following this we can return to this pubic thread with an update where possible.
Thank you for your patience whilst we offer some help and get this sorted!
All the best.
Molly
