I signed up in May 2019. My Wk 3/4 aligners cracked. On the phone I was told that the 1st month aligners would be sent. It's now the middle of Nov & still nothing. I ring, I get promises, excuses. I have all the remaining aligners with me but am unable to start month 2. There was a lot of roughness when I did wear the aligners which you are supposed to file with a nail file but I still had many ulcers form on the edge of my tongue. Customer service has been pointless and dismissive. If I can't START this course I will be requesting a refund. I get text messages telling me to change to Month 4 Week 2 & payments being taken out and no sign whatsoever of Month 1's replacement.
