***** - Contract issued did not apply for contract

Good day I did not take out the upgrade contract with Vodacom for cell number ********** . Since December 2017 an amount of R918.00 is deducted off my account. when I queried it I found that the phone was delivered in JHB and I live in CT. I've been trying to get the contract cancelled with no luck. The assistance from Vodacom is none. I want the funds reversed that has been debited from my account and the contract cancelled immediately.
