Ah yes, 21st C complaint handling..
They hide or remove phone numbers and email addresses. Instead there's a web page with a tab that says "Contact us" that leads to a page of FAQs that have no relevance to anything that anyone would care about. followed, possible only after you've clicked on one of these, by a link that says "Need more help". This takes you to a generic Help page. On that page, carefully hidden, will be a contact us link. Which leads to the FAQ page.........
