Why this answer
What actually matters
- Check the law in force on the conversion date.
- Save the original sign-up disclosure and later messages.
- Challenge unclear, hidden or misleading payment terms now.
- Do not present the future DMCCA regime as already operative.
Important nuance
When the statement may have a point
- A prominently disclosed conversion may currently be enforceable without a universal reminder duty.
- Sector-specific rules or the trader’s own terms may require more.
What you could say
Keep the response tied to the actual rule.
Evidence
What to have beside you
- Sign-up journey, order confirmation and terms supplied
- Trial, renewal and price-change notices
- Screenshots or recordings of the cancellation route
- Payment history and cancellation confirmation
If they still refuse
Move the dispute forward.
- Give clear cancellation notice through a provable channel and identify any disputed renewal or service failure.
- Separate cancelling the payment method from ending the underlying contract.
- Use the trader complaint process, platform dispute route, payment protection or court action as appropriate.
