Can a team-match VP score be negative?
Until a few years ago most Victory Scales awarded negative VPs to a blitzed team. (This link makes reference to such.)

However, by not being at the table on time, ready to play, your teammates are introducing a very disruptive effect on the entire tourney. Your opponents have paid to have an opponent and you have declined to show, for no good reason, and with inadequate warning to allow alternate arrangements to be made. Read the fine print - once you paid your entry fee you contracted to appear and play according to the conditions of contest. Accept your medicine and learn better for next time.

Update:

Alexander Woo's comment to the questions inspired me to check out the ACBL General Conditions of Contest for Swiss Teams. In those it is clear that penalties for tardiness to arrive are assessed in IMP's even when the match scoring is in VP's, although the penalties for slow play are assessed in VP's.

  A team that fails to seat four players by the announced start of a match is subject to
  penalty. The record of a team whose opponents incur a penalty will not be affected
  (improved).
  In addition, one board shall be removed from play eight minutes after the start of the
  match and another board removed seven minutes thereafter. Three IMPs will be
  awarded the non-offending team for each board so removed. If a team has not seated
  four players when one-third of the time of the match has expired, that team shall forfeit
  the match. At any method of scoring, the teams are assigned a result as though the nonoffending
  team had won by three IMPs and the loser is assigned zero. ....
