Hi ron_vdk
To file a INR (Item Not Received) with PP (PayPal) you have 45 days from the time of payment.
"IF" the time expired and "IF" you funded the payment with a CC (Credit Card) then you can call the number on the back of the CC and do a chargeback, they too have a time frame to file.
As for feedback you have 60 days from EOA (End Of Auction) to leave feedback, BEST feedback is calm and factual.
