Nasty response from seller

[cheryl859]

I asked a seller if I could retract a bid. I received a nasty response saying it was not unethical but she blocked my response and me from her site. I would care except I have 100% positive feedback. She blocked my response. I am not sure of why her reaction was so vehement. I have been shopping eBay since around 2003 and have never had such an ugly response. Item I bid on was under $15 included shipping.
