Terrible service - paying for a service I no longer use after cancelling it many times

Hi there

I have been using this service provider called connection. They are basically incredible connection but for online sign ups only. since they have changed to Ignite. I have cancelled my month to month contract with them since august last year. and they still keep re-activating my account and charging me for it. I dont have ADSL at my home any longer so I cannot use the datat that I purchased via them every month. It was an uncapped deal for R199 per month. The line rental was done separately through Telkom and since the cabels that were ****** are not being replaced I no longer use internet at home. BUT I am still being cahrged for the data via Connection.co.za or Ignite.co.za. I have called numerous times with many reference numbers and nobody helps to stop this nonsense I AM SO FRUSTRATED NOW!
