Overcharged for anytime calling

I recently noticed that after cancelling my Telkom ISP account (meaning that I now should only be paying for line rental / DSL line rental) that I seemed to have still been charged close to the original amount that I was paying before cancelling. After contacting support, I found that this was because I had a \Telkom Anytime Extra calling option\" attached to my account. This was a surprise to me because I have never had a telephone attached to my line and have never made a phone call from the line.<br> <br> Although they have now removed this service from my account, they were not willing to discuss a refund / credit for the time that I have been paying for this service simply because it was \"part of a package\". This really comes across as a form of ***** to me - if I did not pick up on this, they would continue to charge me this amount - with no clear indication of what would constitute a time when this service was no longer a part of some arbitrary \"package\"."
