The Follow Up Letter After No Response Complaint is a crucial document in the Nigerian business and consumer protection landscape, designed to address situations where an initial complaint has gone unanswered. This document type is typically used after a reasonable period (usually 14-30 days) has elapsed since the original complaint was submitted without receiving any acknowledgment or response. It serves multiple purposes: documenting the continued attempt to resolve the issue, creating a paper trail for potential legal or regulatory proceedings, and escalating the matter within the framework of Nigerian consumer protection laws. The letter should reference the Federal Competition and Consumer Protection Act 2018 and other relevant Nigerian legislation, while maintaining a professional tone that encourages resolution while highlighting the seriousness of continued non-response.
