Notifications don't work and support won't help you

Neither the customers nor my client nor myself as site administrator receive notifications when a purchase is made. I reached out to support and they asked for my admin info saying they’d be happy to help. Then they said they wouldn’t help because I don’t have a “premium” and “paid” version. There’s no way I’m going to pay for something that doesn’t work. Save yourself the time and headache and don’t use this plugin.
