[Pupart]

I bought some art supplies from a website called Sycamore -Creek.
They accepted Pay Pay so I paid that way.
It has been a month and I have not received my order. I emailed the address several times where money was accepted for this order to try and find out find the status of this order, but cannot get any info. Last night I sent an email and said I wanted a refund. My mail was delivered back to me with a message "undelliverable" .
This order was under $20.00 so it is not a big loss, but still, it's my money!
I filed a complaint with Pay Pal but have had no response to my complaint.
Is there anything else I can do?
