Bad and unfair customer service and practice by Vodacom

Over two years ago I took a 24 months contract with Vodacom. The contract consisted of two phones with their respective data and voice lines (*** And ***). The contract has in fact run its 24 months. It was now running from month to month. For some reason I totally forgot the end date hence it started rolling month to month. On March April 2023 I called Vodacom to note my intention to end the contract. I spoke to an agent who confirmed that my cancellation shall take effect end of March 2023. I was therefore surprised when at the start of April 20223 Vodacom allocated the airtime normally allocated under the contract. Clearly upset at this I wrote an email on 7 April 2023 which I directed to talktous@vodacom wherein I communicated my displeasure and requested that the contract is terminated as per my request. To date I have not received any response to my email save that I am now receiving spam calls around the clock from Vodacom sales enticing me to take a data contract. This is unacceptable and bad. Customers have every right to terminate a contract that has in any way reached its end date. I am very upset in the manner in which I am treated by this company.
