They don't keep their word.
Everything started out fine. Genomelink was supposed to give me one small piece of ethnicity data per week (i.e. one figure per week). That's not great, but I was willing to wait a week for each little bit of info.
3 and a half weeks ago, I didn't receive the promised ethnicity data, and I let them know. They eventually said they'd release the data, but they didn't. Another week went by, still no new ethnicity data. Then another week, still none. Each time, I've informed them. A couple times they've sent me messages claiming they're working on it, but no progress is ever actually made. As I told them, it's a waste of my time to keep checking my account for new data that never shows up. So for not doing what they say they're going to do, and for never fixing the problem, I currently give them a low rating.
