I got an email this morning < 6am asking me for my phone number within 30 minutes or it can't be shipped (in the first 50). Of course, I was asleep in my country (UK). When I asked why he didn't have it he said I didn't fill it in on the website or in PayPal. My number *is* in PayPal and has been for years without issue. As for the website, the field wasn't required so... why would I fill that in? Why ask for it only now? Really tired of all this :')
tl;dr make sure he has a contact number for you asap.
