Hi there and welcome
Can you tell me please on which service you did this? eg: Facebook, Linkedin (as we support a number of services)
in which service was this? eg: Hotmail, Yahoo?
Go to http://mail.yahoo.com
Click the Contacts icon .
Click Deleted Contacts in the left column.- Any deleted contacts appear in the column to the right.
Select each contact you want to restore.- If the contacts you're looking for aren't listed, skip to "Restore your entire contacts list" below.
If you've selected multiple contacts, click Restore Contacts.- If you've only selected one contact, click Restore.
Click Restore again to confirm.- Your selected contacts are returned to your Contacts list.
Click Done to return to Yahoo Contacts.
It is then returned
Let me know how you go please.
