Toothsi — Horrible customer support

I decided to purchase aligners and they were very supportive for a while. I was supposed to submit a few scans and I contacted them after i got them done, but no response from my person of contact. I tried to contact multiple times for a callback and they said they’ll contact me in 24 hours. I didn’t get any calls and I complained again. This happened 5/6 times and I’m sick of following up with this. It’s been 2 months and no progress I’d like a full refund and I’d rather go to an orthodontist instead.
