Service hours amount -- how does this affect chances?

I have pretty decent stats, great scores, essays, etc. but, the problem lies with my community service hours. I have been in 3 service clubs at my school (Interact, Key, and CSF) and have interchanged pretty much every year because of meeting times conflicting with my major ECs, so my filed hours are spread out between all three. Went to CSF, where most of my hours are (meetings are not required) but the head teacher changed and they somehow misplaced my slips. I’m not even sure how I’m supposed to get these filed, and if I can file from different clubs…Help?
