If you receive a defective product from an online retailer: Review the Return Policy: Check the retailer’s return and exchange policies, such as those provided by Amazon under the Consumer Rights Act 2015 in the UK. Initiate a Return: Use the platform’s return process to request a refund or replacement within the specified timeframe (e.g., 30 days in the UK). Document the Issue: Keep records of your purchase, including receipts and any communication with the seller. Contact Customer Support: Reach out to the retailer’s customer support team for assistance. Seek External Help: If the issue isn’t resolved, you can file a complaint with organizations like the Federal Trade Commission (FTC) in the US or the European Consumer Centre (ECC) in the EU.
