you need to make 100% sure the phone works , if it is a voicemail phone or where u need to enter digits to get to reception , they will tell you they could not verify and also
you need to keep pushing it everyday again and again i knew someone his case lasted 2 months with amazon.
Amazon is very difficult now to se if you are going above 500 euro in eu.
I would keep calling them ask for English rep if you dont speak Spanish and explain there further or ask why its not verified.
