Today I woke up to a debit order notification from VODACOM for an account/services I never requested nor received

Today I woke up to a debit order notification from VODACOM for an account/services I never requested nor received. I had a cellphone contract with VODACOM in 2018 and that was paid up in 2020. Last year I asked them to close that account when I checked my credit score and realized that VODACOM still appears on my list of credits and I was promised closure of the account. To my shock this morning I get a debit order notification. I need to know who reopened the account or who opened a new account with my details and I wanted VODACOM to take accountability for encouraging ***** by leaving an account I asked them to close, open. I’ve also sent an email to VODACOM directly requesting the recording of this if it was done over the phone and the address the goods were sent to.
