Left negative feedback because parcel was sent Registered while he wanted it plain mail. Though he never asked before for that.
I explained that since it was a somewhat expensive item $47.5+8.49 we always send registered so would be under paypal coverage.
Unwilling to listen and although the item arrived in tip top condition he left a negative because he didn't want to sign for it !!!
Thankfully, ebay rulled to remove his feedback after reading the messages we exchanged. Blocked him since then.
