Bests & Worsts Reviews from Amazon

So I bought this product back in November 30th as a gift for my sister. She was very excited when she received it and immediately send her saliva sample tube, well it's been four months and she never got her results!! According to them she didn't have enough dna! So they send her another kit she sends them her saliva sample again (she was very careful to do things right) and still NOTHING no results. They tell her yet again she doesn't have enough dna. So they asked her if she would like a refund she said yes this was back in April 9 and she hasn't heard from them again!!She send them the Amazon order ID number just like they asked...so what happened?
