Replying to PayPal struggles

Looking for some experienced sellers to help me figure out what the fuck is happening.

I ordered a $350 Armada jacket a few months ago and decided it was too big.i returned it and the refunded money appeared in my PayPal summary as "+$349.99" but it was never added to my PayPal wallet. It's been more than a month and after several emails, I still can't figure it out. The money isn't available. PayPal and Evo both told me it wasn't their problem. Pls help.
