wrong information provided/ disgruntled Customer

I have a query with Vodacom, I took a Celphone contract that commenced in September 2013, and immediately joined the insurance as well, so last year 2014 I defaulted on my instalment for November, I then settled the instalment in January This year. And my insurance was cancelled in November as well, now I called to get the settlement figure and enquire about insurance T's and C's, I was then told that the contract commenced in January 2014 and that my insurance was for Samsung Celphone of which I never had Samsung celphone. My phone is LG L9. Please sort this out and get back to me with correct details. I even went back Festival mall where is signed up for this contract, they telling me they see to commencement date of one contract of is very alarming, and I have since sales recordings for the insurance to prove to you guys that I never took an insurance for Samsung phone, because I don't have a Samsung phone. surely I need to be refunded all the premiums deducted because I was paying for a product that I don't have.
