They will scam you
I finished up using my credits from 6 months+ ago and got charged for a new subscription. No warning, no confirmation, no nothing. I wasn't even aware I was on a subscription.
Shutterstock had actually gifted me 5 images due to a previous error of theirs, and they must have sneakily signed me up for a subscription during the process.
Now I went to find the livechat to contact them (not easy to find) and while the chat person was courteous, they gave me a templated reply about a refund only being available in certain countries but they'll escalate it and see what they can do. Etc etc. This must happen ALL the time.
My main gripe is that there was ZERO warning of me being charged, and no chance to stop the subscription before it happened. It's like the old mobile phone game tactics from the '90s.
Honestly, it all just feels like an absolute scam and Shutterstock should be ashamed of itself.
