How do I make a formal complaint or escalate an unresolved issue?

If you want to make a formal complaint or escalate an unresolved issue, email complaints@mycosupport.co.uk. This is the complaints route stated in MYCO's terms and conditions, and it sends an automatic acknowledgement so you know the complaint has been received and what to expect next. Include your company name, order email address, company number if available, the service affected, and the outcome you want.

MYCO will review the history of the case and route it to the appropriate person or team. You do not need to attach evidence that MYCO already holds, such as previous support messages, account notes, or internal records. If the complaint depends on something only you can access, such as a screenshot from your portal, a bank-side reference, or a courier message, include that information so the investigation is not delayed.

MYCO records complaint details to investigate and resolve the issue. For how complaint information is handled, see the MYCO Privacy Policy.
