i was denied a dispute because the vendor supposabily sent a tracking number but there were two items on the order and i did receive the one the other on my order says ready to ship but it never was nor is there another tracking number so I guess I am out $16.99 because they believed the vendor

You would lose if you opened a dispute for non receipt and the seller could provide tracking, you should have opened one for item received but not as described ie incomplete order etc.

You are only allowed 1 dispute per transaction so the only way you can get a second dispute opened is to contact Paypal (when and if you can) and see if they will open a second dispute for you.
They may decline citing policies but if you say you made a mistake then they might open a second dispute for you.

If not then if you funded your paypal payment via a credit card then consider contacting your card issuer and see if they will help you with a chargeback?
