I am in the process of registering a new apple developer account for my company. For now I have finished the DUNS code register and applied it for the enrollment. But I received an email said that I should give Apple a phone call from the entry of "Contact Us". My question is I could not find any phone call entry at any time no matter it is operation time or not. There is only one email contact entry for me. So I am very confused and in a great hurry.
