Billed for services not subscribed

I was recently billed R15 per day for a whole month, R450, for a service I did not subscribe for. I was somehow subscribed to a so called "Mira Networks" for some kind of daily "service" I did not use. Telkom is apparently the party responsible for collecting the service fee, but what I find amazing is that their help line cannot tell me what the service is for or provide me with any details about the provider. Telkom have unsubscribed me but true to form they cannot refund my bill. This is so obviously a **** to "legally" de***** subscribers and Telkom obviously receives a nice kickback for collecting the "service fee". Once again the uselessness of Telkom's call center to advise or sort out any type of query is astounding.
