Can Minta charge for a full year without providing services?

I filed a dispute with my bank. They asked for documentation, so I sent them everything I had. They immediately gave me a provisional credit. A month or so later, I woke up to the funds being taken out without notice. I called my bank. They said they sent a letter before they took action. I got the letter a week after they withdrew the money. I’ve asked for a copy of the resolution twice. They said Minta provided 16+pages of documentation. That’s been 7 months. I still have not received anything, except for my bank saying, “oh, they had proof that you owed them.” And shopify saying they couldn’t do anything. Now, I talk to an online support group for boutique owners before getting ANY shopify apps to make sure they’re legit. All reviews on Minta were shady at best. Should’ve checked there first. We live and learn.
