Understand this route
Practical route for “Check a deadline”: keep purchase evidence, identify the proper recipient and check the next action.
What to do
1. First establish whether you have a rejection, no response, debt demand or cross-border dispute.
2. Keep the original notice, response and proof of receipt date; not every complaint has a formal appeal.
3. Use the relevant ADR, ombudsman, ECC or other official route for that type of dispute.
