Contract cancellation fee charged changing ADSL line speed

<p>I contacted Telkom on 18/5/2017 to find out if I can change my ADSL line speed from 2Mbps to 4mbps. I was on Uncapped 2Mpbs and asked if I can just change to 4Mpbs as the promotion running 4Mbps Uncapped Internet is the same price I paid for 2 Mbps. The person named Aaqib (my reference number: ********** 82A) never mentioned I will have to pay a penalty fee or that there is costs involved, but now on my bill I see there is a R621.90 (+Vat) amount charged. I refuse to pay this amount since I cleary asked the consultant about the costs, if there is any reason why I would not be able to change the speed. He only said its pro-rata fee and my monthly bill will stay more or less the same since the service fees are the same of what I paid before, the only thing that will change is the line speed. He also informed me that I have a call plan added and the extra costs will be from usage. Never did he or the person who contacted me after the line speed where upgraded inform me of any contract fee. This is the first thing that should be mentioned if a customer makes an enquiry! The consumer Act says a customer must have full details and be informed of all the terms and conditions and no hidden information! for this reason I refuse to pay the contract fee, my contract wasnt cancelled only the line speed is changed, and the faster line speed is advertised for the same fee I was paying!!! </p>
