Buyer bought two items and paid for each before I could send an invoice with combined shipping. I packaged the two together and printed a shipping label from one of them, so it needs to be mailed today, and I will refund the buyer the difference. I marked the 2nd as 'shipped' but am not able to add the tracking # . How do I do that, or what else can I do? As it stands now I have no proof that I mailed the 2nd item. Tried to be connected to an agent but all I was offered was to email with response within a day, but this package needs to be mailed today. Am very frustrated!
