About the Customer Service Department

When calling Customer Service, you will initially speak to a Tier 1 CSR. Tier 1 CSRs are capable of handling most supplier inquiries. In some cases, Tier 1 CSRs may need to transfer the call to a Tier 2 CSR (also known as the Help Desk). If a callback is required, a Tier 2 CSR will return your call within 10 business days.
