bot acting weired

Hello. Few months back i used the free version of manychat where i used automated comment responses. When people commented on my posts they would get a private reply. It was working well. Then i decided to use the paid version but for some reason I couldn’t pay through my card, so I couldn’t purchase the pro version. As i hit the limit of free use I stopped using manychat from that time. But now i am facing some weird problem where the bot is still sending private messages to the people who are commenting on my facebook posts. And providing wrong information to the people who are commenting. I disabled the facebook page that was connected to manychat and even removed it but still automated private messages are going to the people who are commenting on my posts. I am in very big trouble. Is anyone facing the same problem ? Can anyone help ??
