On Sep 10 I received confirmation that my sons impressions were accepted. We are supposed to receive the aligners 4-5 weeks (4-6 or 6-8 depending on who answers you.) on Oct 25 I asked for ETA and was told they should be done soon. NOW on Nov 20, (only AFTER I inquired) am told somehow our aligners didnt ship with the "others" and that we will have them in 1-2 MORE WEEKS!!!!!!! WTH??? I paid up front in full and someone better be accountable. Im am still unsatisfied today.
