to Funtabulous: I would send a PM, then an email to the address supplied by Paypal, and perhaps wait one more week. When you feel you've waited long enough for a response, you could try filing a Paypal claim (which will only work if they have a balance available). I was very understanding in all my communications, super friendly and gave the seller the benefit of the doubt. You never know what might have happened.
I guess I would just warn anyone doing a Paypal reversal that it doesn't keep the seller from leaving retaliative feedback on your profile here since Paypal and Specktra are not really linked. As you can see from my feedback, I have one hell of a negative --- I also have screencaps and emails that prove I did nothing wrong, but that's not evident just from looking at my profile.
I am embarrassed by this whole thing and cringe every time I think about that feedback. I hate to say this --- even though I know that leaving the neutral feedback (written politely) was the RIGHT thing to do, if I'd known the seller would show up nine months later and freak out at me, I might have done it differently.
