I JUST DON'T KNOW WHAT TO DO :-(

I recently took out a contract for a CPO i phone for R199. I paid 100 and something in the store and my debit order has come off but the phone still won't switch on. No-one wants to help me so I went to the I store which is 76 km's away from where I live. They were so disgusted that a phone had been sold without software!! They can't help me. I'm at my wits end. Surely with a small contract like this they can just replace the phone??? It's not my first contract with Vodacom. I just want what I have paid for!!!
