Soulbound review for Appointment Booking Cowlendar

I installed to test the features, which are quite good. But I didn't end up using it. They still charged me for months of usage, then started spamming me when I uninstalled it. They send an email asking how they can help from a no-reply email that says "PS. if something did not work as expected, just reply to this email. I'm a human and I can fix pretty much everything hehe". When you respond it bounces. Really disappointed in their service. Shameful really. I mean, if you're human.
