Bad support, no refund policy

The plugin may be okay, I don’t know. I got it for a client, but they stopped paying me for it after 1 year. I tried to cancel my subscription, but the cancellation didn’t go through and I got charged for two more years. After the second time, I reached out to support and asked for a refund, they refused to give me one, so I disputed the charge with my bank and put a block on further charges.
