If you're unreachable, that's on you. Can you understand why I'm incredulous to your account? Show me one account of "my voicemail was full" excusing a missed test. Chritine Ohuruogu lost a year because there was a meet at her usual track and she had to use an alternate one and she failed to update UKAD.
Furthermore, even if I give you the benefit of the doubt that you're in this group (which you may be) you don't have a basis by which to cast all others. I'm sure everyone in Sprint Capitol thought everyone else was on something, too. In fact, it was Trevor's selling point (and many others still working today).
