Holding me ransom

A few months ago we suddenly received in an increase on our 10gig top wifi data bundle. We then made the decision to rather move over to an uncapped ADSL line as it would make better financial sense. Since 17 November 2015 I have been trying to cancel our top up contract with no luck! Sent through the cancellation letter on 17/11/2015 and again on 30/11/2015. Finally on 15/12/2015 we received an acknowledgement after I phoned in for the 3rd time to get the line cancelled. I was promised a call back, but more than a month later still nothing! When I try to phone in the agents just keep on telling me that I have to wait for a cancellation department agent to contact me. What??? After more than 2 months!!! I refuse to continue paying for a product I have no need for! <br> Ref nr: ***3<br> An putting someone on hold for 15 minutes with no one getting back to you is inexcusable!
