I need to file a dispute about a transaction that I already filed a dispute about earlier

[EKaTeRiNa7]

I ordered an item. And then something gave that it was a scam. I tried to get money back by filing a dispute but the dispute came back saying that the purchase was in line with my order pattern. But I still never received my ordered item. But now the Resolution Center does not give me a chance to file a "Item not received" dispute as there already was one dispute about the same transaction. I tried message center, same outcome. How can I file a dispute "item not received"? 

Thanks

Sounds as if you opened a dispute for unauthorised?

A dispute for an unauthorised transaction is telling paypal that your account was hacked and used without your consent to make that transaction.
Paypal would check IP addresses and devices and close the dispute if it was you that made the transaction.

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?
