Closing claims without resolving them and no customer service

I returned products to a seller as what they had sold me was nothing like what they’d advertised. As per PayPal’s policies, I couriered the package and shared the tracking details with PayPal for them to share with the supplier on 25 March 2020. I immediately received an email confirmation from PayPal that they received the tracking information and would share it with the supplier. Fast forward to 03 May 2020, I received an email from PayPal denying claim on the grounds that they never received the tracking information. I have sent all proof that This is untrue and have confirmed with DHL that the product is there but have not received any feedback from anyone at Paypal, only the automated computer responses. I have tried many a times to call instead of email, but after a number of options I get an automated message saying they’ve suspended phone services due to COVID 19. Of course the supplier is not willing to do anything as they know they can use PayPal’s policies Like this to get away with ******** people.
