Paying for an empty box!!

<p>Last year I took up a phone contract with Elite Mobile and Vodacom. I was to receive a samsung J1 as well as R100 airtime on a fixed R99 contract for 24 months. When it was time to deliver, there was only a SIM card in the box and an educational books voucher. I called back immediately and asked to have the contract cancelled and they said it will be after they have collected the parcel. 3 weeks later the parcel was collected and a week after that my account was debited R100. I called Elite Mobile who said they logged a cancellation but when I called Vodacom they said they hadn't received anything and will continue to debit until they do. I, the account holder, couldn't cancel the contract. It had to be done via Elite Mobile. But every time I called they said the cancellation was logged. I have been calling since 25 Nov 2016 until now. I am still being debited for a phone I don't have, a contract that should have been cancelled by end of last year. Help! Please! </p>
