I've always been extremely responsive as both a buyer and seller on EBay over the past 10 years. My feedback rating is 100%. I understand sellers remorse if that's what is happening here, i just am not enjoying the weird tactics of the seller. I'd like the bike, just not wild about sending $580 off to someone acting so oddly about this transaction. Claiming to suddenly not speak English when the ad and all of our previous interactions have been in English? That's really reaching!
