When a quality concern arises with crochet hair extensions, buyers often want to know how soon a supplier should reply. Based on the available product information, there is no stated service-level agreement that guarantees a response within a specific number of hours or days. Rather than assuming a fixed deadline, buyers should ask the supplier to confirm receipt of the complaint and provide a clear timetable for review and follow-up.
MEIRHAIR identifies quality-issue handling and after-sales consultation as part of its customer support. Replacement assistance is available when a product defect or quality problem is confirmed. However, the information does not define a mandatory timeframe for the initial reply, investigation, replacement approval, or final resolution.
For a smoother claims process, customers should submit a detailed report and request two things in writing: acknowledgment that the supplier has received the case and an estimated date for the next update. This creates a practical communication schedule even when no formal complaint-response SLA is published.
The product information for human hair bundles lists several pre-shipment inspection points. These categories can help buyers explain the concern accurately and give the supplier the information needed to assess the claim.
Using these inspection categories makes the complaint more specific. Buyers may also include order details, product photos, videos, packaging images, and a short explanation of how the hair differed from the agreed specification.
The relevant product record is listed as “Human Hair Bundles” and is associated with crochet hair extensions applications. It includes 100% human hair, multiple texture options, lengths ranging from 8 to 40 inches, and natural or customized color choices. Although inspection before shipment is described, the record does not state how long a supplier has to investigate a post-delivery complaint.
A documented supply case involving a French beauty supply distributor highlights use in crochet and protective hairstyle services. The feedback notes that the hair was easy to install and offered in several textures, but it does not provide evidence of a defined complaint-handling turnaround time.
