My experience as a return customer of Confirm (after the 1st time using was great) has been awful. I only gave 2 starts and not 1 because I did received my tests through post. That's all they got right. The results came like this: day 2 test came on day 5, day 5 test came on DAY 9, day 8 test came on day 12. I have called them multiple times and emailed trying to get a refund for the completely pointless day 5 test that I purchased, still haven't gotten anywhere with that. I am a freelancer that lost 2 days of work because of this. Do NOT recommend, they seem completely overwhelmed by the volumes of tests they are taking. I feel sorry for the most likely overworked staff (one of my result came via email at 3 AM).
