I received an invoice from Issuu for over $2,500 USD for an Unlimited Annual subscription that I never signed up for. I have never used their service, never agreed to any charges, and suddenly received a bill stating it was past due the same day it was issued. This is alarming and unacceptable.I've reached out to their billing department for an explanation and cancellation, and I'm waiting for a response. If this was a billing error or someone used my details without consent, it raises serious concerns about account security and verification practices at Issuu.Until this is resolved, I strongly advise others to be cautious and monitor any emails or charges from Issuu carefully—especially if you’ve never interacted with their platform.
