Integrity Field Services, Inc. Invoice for over $5,000.00 still not paid. Over 75 days old. Brunswick, Ohio

After signing on with Integrity Field Services, Inc. we have performed work at several properties.  On every job we have completed we have encountered several issues.  Issues include short pay, slow pay, and non-payment.  When we began working with Integrity we were told that we would be paid for our work within 30-45 days.  We now have invoices that is over 75 days old for a total of over $5,000.00.  We continue to get the run around and multiple excuses from management as to why we have not been paid.  We have done everything they require to process payment and still have not been paid for our work.
