Subscription ended early

Ok so my subscription isn’t supposed to end until like mid September, i go on today and cant do anything that i used to and it asked me to resubscribe…..i git 1 year for free and literally 2 days ago it said it was up around 9/19,.,..so wtf perplexity, and you just sit out of with no warning….. This is the most bipolar platform with how shitty customer service is!!
