The last time I ordered from his site I ordered two items. He sent one so I emailed, then emailed again
Then just thought feck it and started the pp dispute. ( you don't have to wait)
It turned up within a couple of days.
I wouldn't hesitate to use him again but transactions like these I have encountered from sellers have taught me to use the protection your given.
Start the dispute at the same time you message with your concern.
Sadly your courteous emails don't carry the same weight as pending action from PayPal.
