LinkedIn Restricted My Premium Account Without Any Reason

My LinkedIn account was restricted for no reason, even though I am a LinkedIn Premium member. I see that random accounts are being restricted, and mine was too—despite verifying it with my passport, ID, and phone number. I use LinkedIn actively for professional networking and job opportunities, so losing access has caused serious inconvenience. This restriction has disrupted my ongoing communication with potential employers and colleagues. To make matters worse, LinkedIn sent me an email stating that once my Premium trial ends, I’ll be charged for a service I can’t even use. It feels like a mockery. Please open my account before charging me.
