Contract fulfillment failure

On the Sat 12 March 2016, I went on to upgrade my Smart S contract and I wanted to take a S7 edge.<br> <br> I went to the 1st Vodacom 4U store and found they do have stock of the phone I want.<br> <br> I specifically asked for the contract Samsung S7 edge+Wireless Charger+6gig Data+Voucher and over the phone they processed my application. Once done they give me the phone and voucher but note dont have stock of the charger yet and will receive during the week and will call me to collect. The following week on Fri 18 March I call the store and they advise they dont have stock. <br> On Tue 22nd I call again they say they will call warehouse and revert to me. The following day I call and they advise me that the chargers have been discontinued and can offer a D-Link Speaker. <br> <br> I have signed a contract with a charger not speaker, so they failed to honor the contract and failed to even contact their customers. Vodacom still advertises the deal on all media yet they cant deliver on their end. I know what I am looking for went I took the deal and they cannot allow people to take deals they know very well they cannot fulfill. I will not accept a speaker, I would terminate the contract if they dont deliver.
