Vodacom SA Terrible Srevice

I no longer live in South Africa and Left my balance in my accountin October 2019 on Zero, the last communication with Vodacom was that they appologised for the errors and mistakes and an instruction was given to the cancelletion dept to close the account on 3rd October 2019, nothong happened and I kept on getting a statement for a Zero balance which i thought they are busy and just taking there time. I now recieve a statenemt for R44.24 for subscription services? My Account is supposed to be Closed, I have a Email form Vodacom appologising and asking for the account to be closed as an internal commonication. This is Terrible Srevice from Vodacom as they have the Ordasity to say that they offer the Best Service in Africa. I have all the mails and communication to confirm and varify all of what I have written.
