Poor Plugin Pro

I was using the free version which worked fine, I just wanted to add the ability to exclude points from selected products. I upgraded to the pro version which caused a fatal error. I worked out that the conflict was between the free and paid versions (with no help from any support documentation or from the provider). When I remove the free version, it then doesn’t allow customers to view their points and it doesn’t then integrate with Woo Commerce account or apply at checkout so basically what’s the point of having it this way as it cannot be used When you go to the site, there are then many extra plugins you need to buy. Very false and misleading and the supplier then hides behind their refund policy. First time I have ever had a plugin that works less when paying for a premium product. Spare yourself 12 hours of pain and buy a different plugin
