Permanently cancel my internet service-living in Greece

I need to permanently cancel my internet service effective immediately or at the end of the current billing cycle.

I am currently living in Greece and cannot make/receive U.S. calls or use callbacks.

Service address: [Edited: Personal information]

I do not want any retention offers, pauses, seasonal holds, or transfers — please cancel the account completely.

Please confirm by email with the cancellation date and reference number.

Thank you,
