My dsis is supposed to have her dhs sample collect by them tomorrow for transport to Prague where she is traveling on Friday to begin her 5th round of ivf. She is panicking as she has had no contact from him today despite repeated emails. He hasn't confirmed that the right paperwork is in place for security at the airport or even that the dry shipper is en route. Can anyone help, she is worried he is a cowboy and so much depends on the sample getting there..
