Could I still, today, get a refund through PayPal?
You can.... it is possible.
I believe the chances of getting a PayPal chargeback/refund are directly correlated to the level of effort (and a bit of luck) put into the process.
First step is to dispute through the website. That'll immediately be closed.
Then follow some of the steps outlined in this thread previously. Persistence and a good attitude can go a long way toward PayPal giving you a refund.
The first time I called the refund was declined. I then asked to talk to thr manager, they seriously just chainged vocal pitches. Terrible customer service.
