How do you handle complaints about quality or delivery?

Complaints are resolved through a structured 7-day process: acknowledge within 24 hours, investigate with batch records and retained samples, issue a report and a corrective proposal (replacement, credit or return) within 7 working days.

Quality claims require batch number and supporting photos; we keep retained samples of every lot for 36 months for independent retesting. Delivery claims are handled against the B/L date with documented evidence.

Report any issue with your batch number and photos, and our QA team will respond within 24 hours.
