How do you handle a quality complaint or dispute?

Top treats complaints seriously: (1) notify us within the validity window with the lot number, COA reference and the issue; (2) we review the retained sample and the batch COA / assay result; (3) if a genuine non-conformance is confirmed, we offer replacement, credit or refund per the contract; (4) for disputes we can involve a third-party lab (SGS, Eurofins) with costs allocated by outcome. Keep the original pack sealed where possible. Our aim is a fair, documented resolution — we do not argue against our own lot data.
