Ban for failing to accept

This happened to me twice in the last day: I get in a game, have my champion locked in, do something on my phone while waiting, someone dodges and I get requeued without me realizing... 15 min ban for failing to accept?! The audio cue for "match found" is too subtle and doesn't sound like it's alerting me to take action.

Please, don't requeue automatically if someone dodges.
