Executive summary

When an online supplement vendor charges a subscription without clear consent or refuses to cancel, consumers should first document everything and try to stop future charges, then promptly use their card issuer’s dispute process and, if needed, escalate to regulators or legal options; federal guidance and consumer advocates stress timely action because card disputes and regulatory complaints have strict windows and different remedies [1] [2].

1. Confirm and document the charge before acting

Begin by reviewing the bank or card statement to capture the merchant name, date, amount, and any transaction IDs, and save screenshots and copies of order confirmations or product shipments — these basic facts will be the core evidence when disputing the charge with a card issuer or regulator [3] [4].

2. Contact the vendor and record cancellation attempts

Attempt direct resolution by using the vendor’s account settings, support email, or phone; if the company is unresponsive or hides cancellation mechanisms, keep written records of chats, emails, and any automatic-reply timestamps because regulators and card issuers look for documentation of good-faith cancellation attempts [5] [6].

3. Use the credit-card dispute/chargeback route — fast

If the vendor won’t stop billing, contact the credit or debit card issuer to file a dispute (often called a chargeback); many guides and the FTC recommend initiating disputes promptly — for unauthorized charges cardholders commonly have about 60 days from the statement date under rules cited by consumer resources, though specific windows vary by issuer [1] [2] [7].

4. Block future charges and consider card controls

Ask the issuer to block future transactions from the merchant or to reissue the card; many consumer reports advise blocking the merchant to stop recurring debits and warn that debit cards can offer weaker protections than credit cards, making a reissued card or block an important practical step [4] [7].

5. File complaints with regulators and use sample letters

If dispute and vendor contact fail, file complaints with the FTC at ReportFraud.ftc.gov and with the state attorney general — the FTC has public guidance and even sample cancellation letters for consumers hit by unauthorized subscriptions, and state consumer protection offices publicly advise this escalation [2] [8].

6. Keep legal and merchant-side realities in view

Understand the other side: merchants may point to auto‑renewal clauses or “terms” and will present evidence of consent, and some disputes fall into “friendly fraud” or billing misunderstanding categories where the merchant contests the charge; if the amount is significant or the vendor persists, legal counsel or a small‑claims lawsuit may be the remaining remedy, but winning often requires proving the billing exceeded the contractual terms [9] [10].

7. Practical tips and evidence that strengthen a claim

Strong disputes include a timeline of when trial periods ended, screenshots of unclear disclosures, copies of cancellation requests, return tracking for unwanted shipments (which some jurisdictions allow consumers to keep if charged improperly), and notes of any phone numbers or failed chat attempts — agencies and issuers treat such documentation as decisive [2] [8] [3].

8. Hidden agendas and what to watch for

Consumer materials warn that some wellness supplement vendors make cancellation deliberately opaque to retain revenue and that industry pressure can shape narratives about “consumer responsibility” for missed cancellations; cite regulators’ advisories and district attorney fraud alerts when arguing consumer protection is the priority [7] [8].
