Just found a fee (2 June) for US$12.99 - NZ$19.08 as monthly membership for Amazon Prime.

I don't remember signing up.

I made an Amazon purchase back in January...

Apparently I may have clicked on a 'trial' button which converts to full membership after 6 months.

I have ended membership now... If I haven't used the services since the fee started I will get a refund.

Here's hoping for a refund.
