Hello,
I think there is confusion.
You using our plugin and another plugin (https://www.ads-software.com/plugins/wc-multivendor-marketplace/) both are different functionality.
Our plugin is for classified listing and another plugin is WooCommerce multivendor.
You write same review for both plugins but that information not math with our plugin like our plugin only 800+ active installation not 10000+ active installation.
As you purchased PRO version you got support. You asked our plugin don’t have registration option but we have registration option it needs to enable from WordPress settings by default WordPress registration not enabled it to need to enable. In our documentation, we mention that unfortunately, you don’t check documentation and video.
I already issue your refund last week.
Thanks
