account was upgraded without my approval

For a while now I’ve been using PushEngage. Seeing that with some other sites I use I’ll get browser notifications, and I wanted the same for my site. I signed up for the FREE plan on PushEngage’s website and installed the WP plugin. Well with the FREE plan your only allowed to send out 30 Campaigns, which is fine. However today my Credit Card was charged and they automatically upgraded my account to Business to “accommodate” my needs, but I never consented to this. If anything I should have at least gotten a notice that I’ve already reached my 30 Campaign limit, but I didn’t, instead they just upgraded my account and charged me. I am getting a refund, but BE WARE! This is a bit ridiculous though that I had to write to them to get a refund. Not to mention that IF the “FREE PLAN” works in the way that where you only get to send out only 30 Campaigns and then it stops working, where instead the FREE plan should work where once you’ve reached your limit for that month, then a block should be inplace, but then it resets for the next months time period. Just about any type of a FREE service plan works in the manor where once you’ve reached your limit for the month, you get a email notice, and then their is a block, but then the block is lifted or reset for the next month period. PushEngage however doesn’t seem to follow this. If they do, then this isn’t happening. I do not recomend using this to send out notifications about your site to your subscribers. Their are other ways to give subscribers or customers notices about anything regarding your site.
