I had trouble voting for Suzanne a few times but kept trying til I got through so it made no difference to the amount of votes she got from me. I doubt people would have given up after getting an engaged tone - they keep trying and probably have a fixed number of votes to give whether it's one or 10 or whatever, so would keep going til they have done their voting.
Seems it was the same for Chris and Suzannes lines so fair for all.
