You couldn't really do that as it wouldn't be fair to the people on those pairs as you'd have 8 people breaking down the lanes and a slower pace of play then the other lanes.
They should have anticipated the need for a breakdown pair and limited the entries to 7 less bowlers, or moved 7 entries to a different region.
Management tried to offer an apology the complaint was forwarded up the ladder, but what could they really do? Restart the whole tournament for them? Give them an exemption into the next round? They had delays but they were able to complete their four games. The people on the pair didn't do great, but they also didn't finish last, and like the OP he bowled above his average.
If it happened to me I'd probably want to do the same thing as the OP did, and maybe his efforts will scare some people away from future AMF events, but there will probably be a much larger majority of people talk about how good of an experience they had.
Sorry to the OP for your bad experience, and hopefully your crusade is giving you a sense of relief.
I didn't really think of how it would affect the other sets of lanes if the bowlers were moved. I guess there really would have been no way of making everyone happy. I just can't believe they didn't have a breakdown set, or anyway of moving the bowlers from the broken lanes. Did they really think the bowlers wouldn't mind the issues?
At this point, there is really nothing AMF can do. Although, I feel they should at least offer some kind of a refund for some of the fees. I also think they should put that center on some kind of a probation or suspend them from hosting a tournament like that.
