Buyer purchased a computer on Amazon. Unfortunately, FedEx lost the shipment. Here is the first email the buyer sent:
"When I use the tracking number on the FedEx website it says the label is printed but the item has not been shipped yet. If this is correct please upgrade my shipping to 2 day priority at no cost or cancel my order and I will buy from someone who wants to do business."

Anyways, I apologized and told him that FedEx lost the shipment and issued an immediate refund.

Here is the second email the buyer sent:
"
Just the other day I tried to purchase a laptop from you and my money had to be refunded because FedEx lost the package. If I placed another order today would you be able to fulfill that order with Prime 2 day shipping or should I send my business elsewhere. Thanks."

I again apologized and told the buyer that I didn't have another similar item in stock at the moment.

After this the buyer left a negative feedback.
