@wasiul99,
I’m really sorry about your bad experience, but at the same time, I feel sad and disappointed because you snatched a change to improve this plugin from me. If you claimed to solve your issue at the support forum, I could solve your issue.
I saw your profile and found that you reviewed with poor stars instead of posting your issues on support forum.
Of course, a review can help us when we decide to adopt plugins/themes (if the quality of review is good). But think about that it would be more helpful for us community if a developer could improve his/her work through good communication at support forum.
We have great benefits from this open source community whether plugins/themes are free or charge. And I believe that you never forget your benefits are a result of community efforts.
