Update: They issued me a refund after I contacted them.
------------------------------------------------------------------------------
They never sent me any renewal notice or receipt of purchase since I signed up for a membership in 2019. I haven been charged every year since (2020, 2021, 2022). I was totally unaware of the transactions since I was expecting any subscription service to send a notification for renewal and receipt after renewal. But I didn't get a single email about it from them which is something I've never seen elsewhere. That 600 dollars was the last thing they will ever get from me. I will never use their site again.
Hello Hua,
