And so it goes on.........not a customer focussed company

I cancelled my contract with vodacom due to poor service, paid the penalties and submitted all the documentation as requested. Received confirmation thereof as well. Just got called by a collection agency for a supposedly account in arrears of R333.42. Look at my statement Account number: I***-3 Statement Date: 03/02/2025. "Total due 333.42 our bank account will be debited with the full outstanding balance as reflected on this statement on the 28/02/2025." and as arranged with a lady that phoned me from vodacom.
