Who is seller "chyoufeng"??

Has anyone had dealings with RS user "chyoufeng" before? I recently purchased several hundred dollars worth of items from them via the RS shop. In my e-mail, I asked for full contact information since the seller is in the UK and I'm in the US. They have ignored my request and haven't signed any of their e-mails with a name. The only reason I have a name at all is because of Paypal. They seem very suspect, so I'm wondering if anyone has dealt with this individual and can assuage my fears of being ripped off.

I'm really hoping that someone can take down their current listings in the market section. There seems to be quite a few people on this board who have had problems with this seller.

What do you mean by problems ??? I just bought from this seller 2 cels, I didn't have any problem of communication with him, but now ... I am worry ! Is someone already deal with this seller in the past ? Any problem happened ?

Wow !!!
That doesn't sound good ... The only thing I can say, she or he replied really fast and offered to put on Rb shop 2 other items of Yue, I got one, I don't know about the other one ... The seller replied "Thank you, I will email you the tracking number tomorrow." So I will see if tomorrow I get a tracking number ... unless I think you can ask for the money back with Paypal, right ?
Thank you Cutiebunny
