Sick and tired of unprofessional companies

Hello Peter, I’m sick and tired of being harassed by Rain. I paid all the outstanding amounts through their appoint collections called NuDebt and they send my an email that my account is closed at NuDebt because I paid full amount. Now few days ago Rain send me an sms that I need to pay the outstanding amount or else they will suspend the services. Whereas I told them I paid everything and I want them to cancel their services because I don’t need Rain anymore I have Vodacom Fibre at home. And the time I was paying them I was not even using their Sim Card Data but they keep on billing me putting my profile on bad credit. I told the last agent I spoke with i want them to cancel the services because the debt is paid up. And I was told that they will give me the credit and I insisted that I don’t want any credit I want this SIM card to be deactivated because I was no longer using it so now I’m surprised why I being billed for something I didn’t using so a long time. Please Hello Peter step in and tell them to stop harassing me with messages and email I owe them nothing.
