Hi there and welcome
Can you tell me how you access Gmail, via your web browser?
Somehow they were deleted by someone, its not common but people can do it by accident.
Can you go to the Trash in Gmail as they should be there (it is listed there on the left) and check for them there.
Let me know if you find them please.
I can also do these steps for you, and have made a request via Additional Services. This is optional, and if you choose to do this, I can, with your permission, remote into your computer while you watch and do all these steps (and deal with any problems that arise during them) for you. Or if you do not choose to take this service, we can continue here. This is no problem at all. Just let me know please.
Can you please return to your question here
Ok, then you will need to use the recovery request.
Use this link to get there please
complete the form and allow 48 hours for the emails to be returned to the account.
If you have any problems, or would like any additional information or assistance, please do not hesitate to let me know.
Else if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
