I have contracted through DSI and knock on wood I have never had a problem with being paid for the work my techs have done. just get in touch with the payroll department at DSI and ask if the paperwork was recieved and get an email address from who you talk to and email them the list of job numbers and ask them for the ACH# or the date it was paid to the company. Then they cant use that excuse again.
