Google + business page verification

Advert test

I am having trouble with regards to verifying my google+ page/google business listings. I did provide a phone number to be used for verification but the only verification option available for my listing is via postcard, that according to them would arrive in my mailbox within 2 weeks. I do not want to use the said verification option since I already tried this before and up to now I did not receive any mail containing the verification PIN from google. Do you think I did something wrong which caused the "bypassing" of my phone number to be used for verification?

thank you.
