Greetings from WP ERP support, hope you are doing great.
First of all, we are extremely sorry for the bad experience that you had with our solution. Since you are one of our potential and active subscription holder, still you own the priority support from our technical team.
After getting this feedback, I have personally tried to reach you to resolve your issue(s). Unfortunately, neither you asked for the support nor replied my mail.
After waiting five days, I am replying today.
However, We always appreciate feedback from our end user. As I mentioned, still you are welcome to take support regarding the issue.
