the platform added 170 new contacts but only 20 messages sent. This filled 70% of my curret plan.

I tested this for 12 hours, I have the trial and I had to upgrade my trial unfortunately because of what happened. The problem was that the platform added 170 new contacts to my plan, but the actual number of accounts that got the message was maybe 20. I’m afraid this tool will send messages to bots, etc. Compared to the 'comment a word' automation, this feels like losing my monthly contact so fast and I went close to the limit for nothing. I regret even running it for 12 hours :( I Wonder if there is any way to repost this? Or did I just loose the contacts for non working tool?
