How to see multiple phone number entries in iPhone contacts?

I have a "contact" in my iphone 5 contact list called PESTS.

I enter new contacts through Gmail and then sync with the iPhone.

Under PESTS (telemarketers and the like), I have about eight different numbers
which the iPhone answers with a silent ring so I am not bothered by them.

When I go into the contacts app on the iPhone, however, only two of the "pests" phone number show up under the PESTS contact. Is there any way to see all of the numbers that should be in there?

Thanks.
