What to do after shipping an item

How do I track my package? What if it’s lost?

The refurbisher asked me to do something and I don’t know how. What should I do?

Why did I receive a counteroffer from the refurbisher?

I haven’t heard back from the refurbisher. What should I do?

I still haven’t received payment for my device. What’s going on?

How do I get my item back if it's not accepted by BuyBack?
