Vodacom daylite *******

Like I did cancellation on *** number last month on 05/02/2020 I even paid more on my paydate they said it was for sim card yes I was ok with but now am receiving invoices that I still owe vodacom the same amount I paid I even called the call center to confirm that my account is closed and went to their store they confirmed that my account is closed so now how am I still getting statements for closed account?vodacom is a crocs network I cancelled my contract cause of their bad service now this will sue now cause you are disturbing my peace of mind this is totally unacceptable.
