This page advertises ball pythons for rehoming. I purchased a ball python for $250 and was told it would be packed and overnighted to receive the next day. Two days later I was told I needed to pay a $400 insurance fee to ensure its safety at the warehouse (wherever that was, I wasn't told). On top of that, I needed to pay an extra $300 for feeding and maintenance, when I was told I would have the snake the very next day. In total I pay $400 and it's been over a week. They refuse to issue a refund because they claim it already belongs to me when the tracking email I received says it never arrived, because it never did.
