Hello,

I would like to know how does challenging rules works...

Is there any way to refuse a match since the level and the game is ok?

Challenges
Any ranked pilot has the right to issue a formal challenge to any other ranked pilot. A match to answer the challenge must be played within two weeks, or the challenged pilot will be rank dropped and lose his trophies. Challenges cannot be refused, but they can be withdrawn by the pilot who issued them.
Challenges can be for rank, to gain a trophy, to seek out a pilot in his home level for a bus driver, or for personal reasons. They can't come with other conditions. Trophy challenges follow the rules for the trophy, and bus driver challenges are in the other pilot's home level. Beyond that, agree where to play or use the random level generator.
You can't issue challenges to more than three pilots at a time, and only three pilots at a time can issue challenges to you. You can't challenge any given pilot more often than once every two weeks. If you issue a challenge and then play the match that same day, you still cannot re-issue a challenge to that same pilot until the full two weeks have passed.
Please take the challenge system seriously, and treat your opponents with honor! You are expected to make a reasonable effort to schedule and play the match as soon as is practical. Letting challenges get close to the deadline is considered a breach of honor; doing it maliciously will result in rank drops or worse.
