There is a good chance that Adecco Staffing may be at the end of their voice contract. The phone number: (502) 732-0450 was ported on 2012-05-02.
If this was a new phone number for Adecco Staffing, it may not represent their contract date. There is also a chance that Adecco Staffing signed a multi-year contract and the contract may not be complete yet.
