Posted thread previous in the wrong section. If someone could delete I would be grateful. My order was suppose to include 1500 pieces and only 1300 pieces were sent. The invoice even says 1300. They buyer also agreed to include extras but didn't send those either. I've contacted him and it's been a day and a half; usually he responds much faster. Should I open a dispute on Alibaba or go ahead and do a charge back. This is my first order with the supplier.
