A few days ago I noticed they charged my card again for auto-renewal.
(Other than calling my bank to block future transcation or switching to a new card) what I can do to retaliate as a consumer/customer? Though it is a small amount (~80USD) I feel so frustrated and powerless in a situation like this.
Anecdotal: I used to be a brilliant subscriber myself, albeit one who fell into the annual subscription fin trap. Meaning, I slowly stopped using it and ultimately forgot I had a subscription. So I ended up shamefully charged a full year and a half of non-usage. I thought about disputing it but knowing that it was ultimately on me to have been more responsible my only legit option was to just cancel the subscription and do some proactive checking that I didn't get charged again. Which I just did after reading your post. Would love to hear what kind of life hacks other folks do to stay on top of subscriptions (outside the obvious ones which I've already admitted too not doing of course) ;)
