The letter includes and affidavit for me to sign and demands that I send in a payment of $919.32. I did sell a box set of Zumba DVDs on ebay but I had no idea they were counterfeit, I purchased them myself on ebay and sold them because I preferred to do Zumba with other people at the Y. I did not say in my description that I got them directly from the website or try to be misleading or anything--I merely stated that I was selling them because I didn't use them, just like I do with so many other things. The discs played fine and I did not get a complaint from the buyer or anything. This feels really crazy and very unfair--I am being lumped in with jerks who knowingly scammed people and/or were mass sellers when I sold ONE,and the firm doesn't want to hear any individual excuses-pls advise!Something I failed to mention previously is that the letter I received seems to be a form letter sent through my email address. They do not cite specific information about me other than that I sold the Zumba box set on ebay, the one they allege to be counterfeit. In addition, I purchased the box set thinking it was USED and also sold it as USED. There was nothing out of the norm about it, looked "real" and I played each DVD and they all worked fine with nothing that would have indicated to me that they were of questionable quality in any way and when I sold them I said in my listing that I had watched them but preferred to do the class at the Y and that was my reason for selling them. So the buyer knew they were used also and there was no complaint from them about the DVDs quality or anything like that. I'm thinking I was just a name on a list generated of anything Zumba related sold on ebay during a frame of time maybe?
