Unauthorized Contract Upgrade Done by Consultant

My Vodacom contract expired on the 29th of November 2015 and i did not renew it. i only converted it to a recurring 3GIG contract. A consultant and her manager in Dundee on the 29th of December 2015 upgraded my contract without my consent. i immediately called Vodacom because i was in Pretoria at the time. i made an Affidavit in Roslyn Pretoria same day and the following day i went to Vodaworld and a consultant emailed my documents. i was told they were never received and i faxed them to to *** and ***on the 31st of December and the 3rd of December and also on the 7th Of december. everytime i call vodacom they tell me they never received my documents. i suspect Vodacom is protecting their ******* manager and consultant because why else would they cancel my service request and create new one and cancel it again. i am fed up
