Empower Shipping

Hi,

So I signed up for POM in January. I paid for 6 months upfront.
On Jan 23rd I received my first two vials.

In March I received two more vials.

Today, I got vile number 5, but it was by itself. I should technically have one more coming so I’m confused why I only received one today when I’ve been getting two at a time?

I tried looking on the website but there’s no info anywhere. I’ve never recieved tracking for any of the shipments, they just show up and I tapered slower than directions so I haven’t needed them on time.

Has this happened to anyone else and the last vile was shipped separately?
