Unhelpful and unaccessible - broken site and loss of funds

I have escalated a problem to PayPal for items received from a seller that doesn’t match the specifications of the items I purchased. It has netted out that the seller is prepared to refund me the cost of the incorrect items. I am unable to access the resolution center to respond to the sellers communication and PayPal is extremely poor at helping me with the issue. I am running out of time to respond the the open case and am at risk of losing the refund. I have reached out to PayPal via email, Twitter, Facebook, Facebook Messenger with no resolution to THEIR technical issues that are causing me to be out of pocket.

In addition to the above issue, I had unauthorized activity on my account which PayPal very quickly rejected / declined the escalation and closed the case. I’ve had to cancel my credit card and am still fighting more than 2 weeks later to get my money back.
