The Strong Mail To Vendor For Poor Service is a critical business document used when standard communication channels have failed to resolve significant service quality issues. This document type is particularly relevant in the New Zealand business environment, where it draws authority from robust consumer protection legislation including the Consumer Guarantees Act 1993 and Fair Trading Act 1986. It serves as both a formal complaint and a potential prerequisite to legal action, documenting specific service failures, attempted remedies, and clear demands for resolution. The document should be used when service issues are persistent or severe, when previous attempts at resolution have failed, or when immediate corrective action is required. It typically includes detailed evidence of service failures, references to contract terms, citations of relevant legislation, and specific demands with deadlines.
