Vodacom marketing targeting minors!!!

Without permission/authorization to be contacted for promotional products, Vodacom is contacting and telemarketing a secondary educational device I the contract, holder took out for a minor child. This is unacceptable and the persistence is nauseating. Vodacom, please provide evidence where I consented to be contacted for promotional marketing. You are in breach of contract, harassing a minor and acting with ********* behaviour.
