I’m using ChatGPT plus. A couple of days ago it said that I had 15 deep researches left about 15 minutes later it indicated that I was out of entirely so now I’m being asked to pay $200 in order to continue I don’t have the option of opening another account under someone else’s name but I would like to know if I’m going to pay this why it tells me I have 15 left, and then it suddenly cuts me off.
