Vodacom not contacting me as promised

Cannot give negative stars or none. I wrote a review about my terrible experience with Vodacom since August last week Thursday. Vodacom was very quick to respond that someone from Vodacom will be in contact with me soon. Well ... eight days later and still nobody contacted me. I did get automated messages providing instructions of paying an arrears amount, except there is no arrears amount!! The actual issue of ignoring a contract cancelled with the 14-day cooling off period and trying to bill me for it is still simply ignored, like it has been ignored for 11 weeks now.
