I opened an account couple of weeks ago, I tried to build a chatbot but didn't finish. Today I login again and it says that my limit of 1000 income messages was reached and needed to upgrade. but I haven't even build one chatbot. how is that possible? the same happened to me with my playgund (chat gpt) account. in both only open the accounts and leave them there for few days. I login again and says that have reach limit. Can someone help me with this please? What or why this happened? Thanks in advance
