There's no harm whatsoever in giving them your phone number. Really, you've already told them your name and the exact location where you live, what more harm could they possibly cause you by having your phone number than they could by having your name and address?Got the approval e-mail, but no way in hell I'd give them my phone number. They don't need it to contact me.
So I just sent them the other information, omitting the phone number and saying "You don't need my phone number to contact me."
