<prompt> Human: I had been receiving invoices from a newsletter distribution service for the past two months. I ignored them thinking it was spam, however today they sent me a letter of termination and asked me to settle my open invoices worth 300 within two weeks or they would involve an international debt collector agency.Is it possible someone used my email to sign up to their service ? How should I deal with this to avoid paying and legal trouble ?This company is based in Germany and I am from India.  <response>: Not sure how international contracts work but ask them to send you a contract you have signed to agree to the service.
