Update: No longer disappointed! Confused though.

Despite the tracking I saw earlier this morning telling me that my kit was being sent back, I have finally received my package. Not sure why it said it was being sent back earlier, but at least this part is resolved.

Sorry for being fussy earlier, I think maybe some other unhappy posters here got me anxious about it. I'm looking forward to finishing this experience and seeing what insights I can learn from Sequencing's wgs service.
