Contract started too early - all benefits removed

My Vodacom contract is coming to an end at the end of June. I contacted Vodacom to review my contract as i will be overseas for 9 months and i don't need the current limitless red premium package. My needs confirmed to the consultant were that i only wanted data and wanted to be able to share my data with my family as i currently do on a monthly basis. I also asked him to only start this contract when my contract ends so that i do not have to pay any cancellation fees. To my disappointment just as i arrived overseas i realised that i couldn't share any data anymore and that i was removed from the red package with all the rewards and benefits and this new data contract was already activated. Please assist me urgently via whatsapp as i can't receive any phonecalls or make any phonecalls or alternatively contact my friend who is posting this complaint on my behalf.
