Hi Z0MBIE ALICE,
I too am level 3 in-game on RS3, but haven't had anything like that happen to me. What it sounds like that ultimately happened was that you had accidently selected the wrong skill to gain xp in.
If you truly believe there was a bug, and no way you'd accidently clicked on something that could give you any combat xp, like a combat dummy, the wrong skill on an xp lamp, etc, then send in a bug report in game. You can right click the red report button, then click "Report Bug" to do so.
Sorry to hear about the combat levels!
Keep it fun, friendly, and helpful.
