Perplexity is STEALING from users, violating Law and hiding behind their AI bots Sam
This is not about the money. It’s about the principle. We are constantly told that AI is here to "help" us, but multi-million dollar companies like Perplexity are weaponizing their own AI to steal from regular users, stonewall our complaints, and blatantly violate consumer rights. It is systemic corporate greed, and they are getting away with it because people are too exhausted to fight back against a machine. Well, I am fighting back, and you should too. Here is the absolute scam Perplexity is running right now. How they steal your money: Living in Latvia, I pay for my Education Pro subscription in Euros (equivalent to $10/month). April 27: A payment was due, but my card declined. Fair enough. Perplexity froze my account immediately. I had ZERO access to Pro features. May 16: I manually paid for my subscription to reactivate it. The payment cleared. May 29: Barely 13 days later, my account was stripped of its Pro status and locked again. When I demanded an explanation, their billing system's "logic" was revealed: They took my May 16 payment and retroactively applied it to the "past due" period of April 27 - May 16. A period where my account was completely frozen and the service was actively withheld. They effectively charged me for a full month of service, gave me 13 days of access, and pocketed the rest. This isn’t a glitch; it’s unjust enrichment. It is theft. Enter "Sam" the AI If you try to get your money back, you don't get a human. You get "Sam, the AI Support Agent." I tried to explain that under European law, you cannot charge a customer for digital services you didn't provide. Sam’s response? A pre-programmed loop denying my refund, claiming I was "outside the 14-day EU refund window." Here is the most infuriating part: I did submit a ticket well within that window. But their automated system closed it without resolving it. When I pointed this out, the AI literally replied: "I don't have access to separate ticket histories." They use their o
