Before the technician is on the way
You can cancel or choose another window from My B1 at any time until the technician starts driving to you. The card hold is released at once and nothing is charged.
Once the technician is on the way
The cancel button is replaced by a message to B1, because a technician is already driving to you. [Owner: whether a trip fee applies, and how much.]
If B1 has to cancel or move a visit
If no technician can reach you in your window, or we must cancel, we tell you as soon as we know, release the hold, and offer another window. You are never charged for a visit that did not happen.
If nobody is there
[Owner: what happens when the technician arrives and the vehicle cannot be reached — wait time, and any fee.]
