Pre approval got rejected 3 times in RAKEZ

I am thinking of moving to Dubai from India. I have started the company registration process, but my pre-approval has been rejected three times.
My agent says some Pincodes get rejected if they come under red alert. After some time, when the PIN code status is restored, immigration starts approving applications from the Pincodes again, so we need to wait a month before re-applying.
Has anybody faced the same issue? What do you think I should do? Should I wait a month or apply to another free zone?
