Go to Verizon and they should give you a correctly sized SIM card for your phone and activate it for you. So long as it is a corporate Verizon store, it should be free of charge. Some of the premium retailers charge for them so be careful.
Alternatively, you can use some thin cardboard to create a frame to hold your Micro SIM so that the gold contact is in the right place. So long as the contact is held, it will work.
