Not taking Accountability

The policy to me was sold at the store by a consultant representing Vodacom store and Vodacom insurance so in this case who needs to be held accountable for the consultants negligence in submitting the insurance forms that I filled out in agreement to take insurance for the device. As per agreement when everything was explained , money going of my account was inclusive of the insurance.

Please advise if you will be able to question Vodacom insurance company regarding the above. Please advise whom else can I escalate the above to as I don’t have an attorney to represent me . I am a citizen whom is just a living wage against a company whom doesn’t want to take accountable of their *********** consultant.
