********** charges for the 2nd time!

This is the 2nd time now that Telkom has billed me for a service that I did not subscribe to and now I am R303.00 over charged! After doing research on this subscription of what company they said it was for, an 'Akinga' , this is actually the telkom plus service. When I call the call center the consultant just tells me that they can't refund me because I subscribed to the service but I keep telling them I DID NOT!!!! When I ask for a manager they can't give me a number to call all they can do is send them an email to call me back which never happens. I even asked for the email address but that bounced. And to make the matter worse and more ridiculous is that the subscription is being charged on a data sim card which is in a mifi router that I have a contract for and is never put into a cellphone. Telkom is just a *****!
