Query: Two Pack = one

Ordered this thinking I was ordering a 2 pack. But, I only received one. Chatted with customer service and she tried to convince me that this 2 pack meant only 1 refill. Huh?So, seeing as I could not convince her that I was right and that 2 means two I am sending it back. I can go to the pet store and get one for $5.00 Since when does a 2 pack mean one? Someone here is living in another dimension.
