Terrible when things go wrong and stop replying to messages on my account. Clearly focused on selling to new people more than making existing clients smile. This guarantee on the website is meaningless (just read the small print). But more worrying is the attitude and lack of delivering on the values they claim to have. Left with straighter teeth. But without comfort that the issues my dentist says could cause cracking of teeth. They do not have official complaints process. Will not reply to requests for the medical professionals details responsible for the diagnosis that conveniently claims they are not responsible for my issues. (something 2 dentists that have seen me in person refute) Will not provide any details of independent body or ombudsman. Without a reply to this I will have to escalate to general dental council. I have no choice as could end up with cracked teeth or a big correction bill
