Lionbridge Employment Verification/Contact Information - Mortgage, Please Help!

Hi everyone!

I've been working with Lionbridge for about two months now and I'm in the process of buying a house. The lender needs to verify my employment with them and wants an address and phone number - I've looked on all the information I've been given and can't find anything other than an email to contact. Does anyone know their address or phone number that is for independent contractors?

​

Thank you in advance!
