Going in circles and getting nowhere

On 25th July 2015 I cancelled all my Telkom services. A final amount outstanding of R769.38 was due in final settlement and paid on 6 August 2015. At the same time the call centre informed me that they could see that the ADSL services had been cancelled but not the internet services. They would put in a request to have this cancelled too. A month later I received another bill from Telkom charging me a Service Fee of R553.16. I phoned 10210 again and this time the operator said they would put in a request to have the amount reversed. I was then notified that Telkom had blacklisted me and have been inundated with debt collectors calling me from various companies. I finally went into a Telkom store & was informed I had to call 10210. I called 10210 again spoke to S.Nkayi who requested head office to call me as 10201 can't handle a blacklisted query. Needless to say I am still waiting to speak to someone in Head office. This is so frustrating!
