Last year I signed up for YouTube premium, but cancelled it after a few months.
Then, a few months later, I noticed that Google was still billing me -- so I put in a complaint and explained the problem and pointed out the receipts I had... and they just rejected my complaint after "careful review" (lol) and didn't reimburse my money.
It was only about $75, but I remember thinking to myself that Google is obviously going to &%^.
I felt like I had no recourse and Google had just stolen $75 from me and then told me to #$%^ off.
