Operator should be able to see from your logs which rounds are counted against wagering and which not. Was it some specific slot you played which didn't count them or same with all slots (if first one, can be that game setup was incorrect when added to site and didn't count against your wagering)? In any case, they should be able to figure it out and correct it, would guess that support people don't have access and authorities to change game setups but it must be done department who will add these games to site, under right category, bonus wagering % and all everything else where your gaming and wagering history can be counted.
If problem was in all games on site, they should still be able to see exactly which stage wagering stopped, especially if it was only one game which didn't count it as it should, it makes it very fast task and even if it was all of them, it't not rocket science to count all your played rounds and manually take it off from your WR. Shouldn't be hart to sort out now on Monday (if it's not that late that nobody available anymore who know and have access to do it).
Hope you get it sorted.
