CONTRACT PRICE PLAN OVERCHARGE

On 10 September 2015 I went to VodaWorld to upgrade my contract to a Smart XL price plan from a business 500 the signed contract is for Smart Xl total premium R1098<br> When I received my first invoice they charged me for a red premium subscription with extra handset and insurance etc. total R2291.69<br> I went in to Vodacom Menlyn in October and they said it will be fixed <br> I call the guys at call centre, Jabulani and he told me he can't help me systems off...?<br> I made a few extra calls and no one can help me.<br> Then I got hold of KEA the lady who helps me with the upgrade and she said she will check it out and let me know.<br> She phoned me and said her supervisor is in a meeting and they will rectify the problem...<br> Week later and no feedback....<br> They overcharged me R2200 total?<br>
