I still haven't received my iPhone from ebay?

I booked iPhone 5 on eBay a week ago, I. I should have received it yesterday. I didn't get it, what can I do? Do I need to ask about this problem from eBay customer service? Two days ago I that message that item had already been shipped. I don't know what do?

Generally, items and packages will arrive 2-5 business days after being shipped from the location you're receiving it from. That being said, they won't arrive on Sunday or Saturday or a national holiday. So after three more days and it's still not there, you may need to contact someone.
