I buyer has brought two items from me, and requested them to be sent same parcel. I go to post office next day with address ebay has provided me with and pay for the most expensive service so it could get to them next day. I then go to add tracking number on Ebay, and it telling me I got to use another service using a different tracking number. I then look up the address I sent to, and it turns out to be a delivery office. So i ring them up, and they explain to me everything will still get to its destination but I got no way of tracking it since it has arrived at the destination ebay provided me with. I tried, and spent many hours trying to sort this out, and my buyer hasn't replied since. I feel like I'm going to get scammed, and I'm lost as what yo do?
