Unfair cancellation policy.

I want to cancel my Vodacom mifi device. The cost to cancel is more than the cost of paying monthly for the next year when the contract runs out. So it costs more to cancel and not have the service. Surely this is nonsensical. They say there is a discount app**** so charge me for the discount and bill me for the remaing amount on the device. The data you aren't supplying so why charge that. This would be fair but not a practice of billing me more than the contract period! I'm sure Vodacom will reply saying that a consultant will contact me shortly and as per many other of the HelloPeters no one will contact me. The business is running an unfair practice and customer service no doubt just has to push the messaging from up top.
