I have reached the maximum capacity of GPT-4.5 on my current ChatGPT Plus subscription. The system prompted me with an Upgrade to Pro button, offering me access to the ChatGPT Pro plan – priced at €230 in my region.Naturally, I assumed that by clicking this upgrade option, I would gain access immediately – especially since this is a high-tier and expensive subscription. However, after upgrading, I was informed that the Pro plan will not activate until an entire month from now. Even more confusingly, my existing Plus plan, which was due to end on July 19th, has now mysteriously been extended until August 4th, without my knowledge or consent.This delay makes the entire upgrade system deeply frustrating and highly impractical. Why offer users the option to upgrade, if that upgrade doesn’t actually take effect for another 30 days? I urgently need access to the Pro tools now, not a month from now – I am working on an academic project with strict deadlines, and this interruption significantly affects my workflow.It’s extremely disappointing that such a costly subscription – €230 – comes with this kind of user experience. I feel deceived by the misleading interface. If Pro access isn’t immediate, the system should make that explicitly clear before payment. As it stands, I paid today and received… nothing.Sincerely,
