How do I contact support if verification, renewal, or mail handling is stuck?

Contact the relevant team through the client portal, support email, phone, or live chat during published business hours. Include your company name, order email address, company number if available, the service affected, and screenshots or payment references where relevant. If you are waiting for a verification, renewal, or mail-forwarding email, check spam/junk folders and search for messages from MYCO, Sumsub, accounts, or renewals. If an issue is urgent, explain the deadline clearly in the subject line and message.
