Of course they won't do anything. There's never been any absolute concrete proof that any estate timers are bugged/flawed, so it's your word against an automated system. Unless you've got dated screenshots, there's no way for you to validate your claims. Further, there's.. probably no system in the game capable of replacing your house short of rolling back the entire instance/server. And that's just not feasible to satisfy one customer and piss off dozens more.

There's an Estate Timers window for a reason.

Additionally, you make an unclear point about it being your house. If your wife got the dream plot, would it not be her house? As a tenant, you are not capable of resetting estate timers, only the plot owner can do so. Your entering the house would have no effect if it was owned by your wife and she failed to reset the timer herself.
