UNWANTED DATA CONTRACT

when my cellphone contract expired on the 30 November 2023. They offered 800mb for R99.00 I refused to accept that contract. Telkom still continues to bill me for this nonsense. And had handed over the debt to NU Debt. I am fed up of their harassment of e-mail and sms. Please don't force unwanted contract. Dont force business for life. When a 24 month contract has ended dont unilaterally come with your own terms, And expect payment.
