I cancelled tidal after the trial. I figured aout a few months later they were still charging me. I checked and indeed my account showed cancelled took me forever to get ahold of them. They had 2 accounts for me and I had cancelled one. They contended I accidentally opened a new account trying to log in. I suggested something more nefarious. they refunded a couple of months but not all of it.
The credit card said they provided the service, even though I didn't use it, and would not reverse the charges.
