Vodacom & Vodacom Insurance not willing to help customer of 15 years

Recently got a contract with Vodacom and also insured my device with Vodacom Insurance. I signed a contract to pay R189 for insurance per month. After I received my invoice it stated that the amount for Insurance is R200. After numerous calls to the insurance company and driving back and forth to the Vodacom store it was realised that the Vodacom Store has the outdated forms and that the Insurance company has the updated one. Also realized that the contract signed for insurance does not even get sent to the insurance so they actually have no idea what you signed for. I stated that it is not my problem that the communication between the insurance and Vodacom is up to Sh#t that they let customers sign the wrong forms, but that I signed for R189 and that is what I am prepared to pay. The Insurance stated that they will phone me within a week as to how they will refund me or correct this matter. After a week I received no calls. I called again and to my disgust no query was even logged.
