What was the exact error when you used the USB recovery stick? Did you follow these instructions: Go to https://support.microsoft.com/en-us/surfacerecoveryimage
(with a different Windows computer if yours is not working properly)
and download a recovery image for your Surface. You will need a 16GB or 32GB USB stick (also called a flash drive) formatted FAT32 (use a Windows computer). You can't use an actual external USB hard drive for this and don't use anything larger than a 32 GB USB stick. Best to purchase and use a new, previously unused USB stick for this. Use FULL format and not quick format and give the volume a name like surfboot. Unzip/extract the recovery zip to the root of the formatted USB stick.

You can use a phone to contact support https://support.microsoft.com/en-us/help/4051701/global-customer-service-phone-numbers - ask for Surface support. Use the phone numbers listed under *For Business Users* for your location (these also work for consumers/home users).
