What I will do now is I will write a message.

How's that for style, eh? Goes hand in hand with "What we're doing here is we're...". It's one of the dumbest crutch sentences I've ever heard - and it's completely redundant. "What I will do now is " and "What we're doing here is " can be completely erased without affecting the meaning of the sentence in any way. OK, doing no damage, at least. There's a side effect, though: the sentence becomes shorter and clearer and sounds less stupid.

Sorry, had the radio on during lunch, and heard this at least four times. Tried to eat faster, but couldn't match the speed of the audiologist lady on air.
