Case details : I bought two UMD discs for Sony PSP. I didn't get any reply from the seller on writing to him or any update on shipping information. Though it was still within the time duration, I went forward and called him. I was told by the seller that one of the two items was not available. Thankfully the seller initiated the refund from his side after the phone call.
As you can see, the seller has a good base. Lots of feedbacks (positive feedbacks, I guess from the time when sellers could leave negative feedbacks for buyers too). Yet I got to know the state of affairs after calling him.
To add more to it, I was offered that I could opt for another UMD if I wanteed and we would adjust the funds. I went through his items for sale on ebay and thought of buying 'Dexter' another UMD "listed by him for sale" but was not available.
