Scam company
HumanFood will charge you without permission, ignore returns/refund requests, deliberately make it difficult to cancel a subscription that you never asked for, and continue sending you bars no matter what you do.
Don't believe their "ethical" front, this is far from an ethical company. I had high hopes based on the nutritional and environmental promises of the bars themselves but unfortunately I was intolerant to them so I didn't return to order more after the trial pack. Fair enough, not everything is right for everybody, that's why there is a trial.
However, little did I know, they secretly sign you up to a subscription with the trial pack, so a few days later I was charged for a large box of bars I had no use for. While this is relatively common practice, most companies are much more transparent about this and send you warnings about upcoming orders with easy links to change them in case (e.g. Huel, Grounded, Apple).
I eventually figured out how to cancel it (deliberately hidden in the website's design), and paid my own postage to return the unopened box.
Not only did they never refund me for the return, today I wake up to ANOTHER ORDER they're sending me.
Avoid this company and go buy Huel bars instead... or just make your own, it's less hassle.
