Refusal to cancel incorrect contract from telesales..

<p>In March 2015 I was offerd a Data deal via Telesales from Vodacom. The wrong device, data volume and cost was received. I contacted them immedially and was promised it would be sorted out. The device was picked up inMay 2015. This has been confirmed. I am still being billed and pay for this contract. They refuse to cancel it. I cannot stop p[ayment as I have a few contracts with them.All EMails to customercare are answered ( about10 and sometimes a consultant calls me back. To give you a bit of HOPE they make promises that they will sort it out. I went as far to see when it would be cancelled and was informed by that department that they have heard NOTHING and it will be inforce till the end of the contract in 2017.</p>
