This is an *********...

This is an ********* company that has been so unprofessional and rude over the phone when I asked for information on the sms and emails that I receive and continuous calls for an account that was taken in 2016 and closed in 2021 when I was retrenched but they are threatening legal action 9 years later....I am unemployed and have taken no loans since 2021 when I got retrenched, so why do banks hand over closed debt to this company who cannot even share details
