RMA?

Has anyone ever RMA’d something before?  I bought an eVGA video card off of newegg.com, and they said that I needed to go through evga for the rma (it went bad, think it was the ram on the card), so, I goto evga’s website, and apparently, my video card is registered to someone else, not cool, so i email them, and they get everything sorted out, and they authorize my rma, and i ship it back to them, last friday, 3 day, and they signed for it on Tuesday.  I paid 15 dollars to RMA it, another 20 for them to ship it back 3 day, plus the 20 for shipping it to them 3 day.  So, 55 dollars.  Well, I still haven’t heard anything back from them, and my video card still isn’t here, and I haven’t received any answers to my emails to them about the card.

What do I do?  I mean, I paid for 3 day shipping, and obviously, this isn’t 3 days worth of shipping, now, granted, it should possibly take them a day or 2 for processing, but, in that time, shouldn’t there be some form of communication?  Especially since I emailed them not only the tracking number, but also because i have emailed a few times about the status of it?  What are my rights?  Does anyone know?
