Vodacom contract breach

Good day, Referring to complait you have already received: "At the end of June I signed a contract at Game Somerset Mall for a Vodacom contract for the Smart L+ package for R419 per month as stipulated in the signed contract. VODACOM now montly bills me R699 as this is the normal price of the contract. It has now been a two month struggle of constant calls and visits as Vodacom says Game needs to provide the discount on their system but Game refuses to do so. I signed a legal binding contract for the Smart L+ Package for R419 and that is what I should receive at that price. I NEVER AGREED ON R699 which they now debit me monthly and refuse to rectify. I have now been charged R699 for two months. With no credit to my account" We have been promised over and over again by your staff BARBARA, at Somerset Mall branch that our problem has been fixed. Once again I have had a debit order gone off for R700 WHEN THE AMOUNT IS MEANT TO BE R420 as signed per legal binding contract signed at Game Somerset Mall and my account has not yet been credited. Your staff Barbara is now also on vacation I am sitting here at a loss monthly with no one to resolve this. I am hereby informing you I will be laying a complaint with the National Complaints Comission against Game as Vodacom has time and time told me this problem needs to be resolved by Game. Lee Lackey has also not yet contacted me in regards to the matter. Neither has senior management done anything to resolve this. Please advise soonest.
