Not honouring their deal

<p>I took out a new contract as I saw they had a special online. I got approved instantly for a new contract and got a confirmation call confirming delivery only to find out a day later afte another call that they now want to change the deal and charge R450 more monthly because the phone they were going to deliver is discontinued. The phone was not discontinued and the deal was not correct on the site but I was approved and have confirmation mails and screen shots. That is the price they advertised and that is the price I got approved on. I want this concluded by Vodacom honouring their deal. reference number ********** 9. Please get in contact to me so we can conclude this</p>
