I enable login approvals on two of my facebook accounts.

I tried logging in and was told to use the code that would be sent to me.
I've waited for more than 30mins and the message (code) has not arrived.

It doesnt take so long in the past, but now am totally fed up with it.

From trying to provide security to my accounts it seems i've locked even my very self out of it.

I can't use any of the accounts now. Previously today, when i tried logging in, i encountered the same problem, though the messages with the codes arrived very late, i had already closed my browser and was doing something when the message arrived, and of course i can't use the code as at the time it arrived because it must have already been invalid.

This thing is making me loath Facebook. I recieve notifications of what's going on in my accounts, yet i can't log in to access these notifications simply because of this goddamn Login Approvals.

Does someone out there know a possible way out? I've reported the issue via their Help Center, and am still waiting.
Thanks to Nairaland, where else could i have turn to , with my fbks accnts forcefully locked!
