Left with no support - interpreters not being paid.

AtW have not paid any of the interpreters invoices and now my interpreters are not able to continue to work for me, leaving me with no support. It is not fair on the interpreters who are working but then not paid or me. My interpreter told me that they can't even contact AtW to chase up their payments.  This means I am under pressure to sort it out when I can get no response from them! Very Stressful.
