Paying for a phone that I never received

My aunt and I took out separate contracts for each of us last year 24 November (BLACK FRIDAY DEAL) and we am still waiting for one of our phones that we were supposed to have received. Almost 4 months after we took out the contract I am told the phone is on the way. When I tell the consultant that i no longer want that phone but something better than what i was supposed to received she said " that is what you signed for". I can not buy a phone for a certain amount only to receive it 4 months later when it's value has gone done drastically.

Yes I was supposed to a particular phone upon signing the contract, which is drafted by you vodacom, however you failed to abide to your agreement/contract.

If I am not going to be compensated for bridge of contract and paying 3 months for a phone that is gathering dust somewhere at your warehouse do not even think about contacting me
