'Revert' is usually used when we talk about returning to a former state/condition/habit/topic of discussion' or in legal language/contract, etc. eg. property revert to the state., etc.
Thus, I am doubtful that 'revert to you' is correct English. Yes, I've seen it used quite often in this part of the world.
I would prefer 'get back to you' or 'reply to you'.
