Twenty20 offered a trial to download up to 5 photos. I never used the 5 downloads because we were not happy with the images we were finding on the website. I stopped using Twenty20. A few days later, they charged me for an entire year of their product without any warning.
Obviously this is a mistake and should be refunded, so I reached out to support. Support told me that they will not refund me after explaining that we never got through the trial and have no intention of using the service (We're now using Deposit Photos which has been outstanding so far).
Never use Twenty20.
