Its over a year and still have not received Phone.

I sent in my damaged phone as it is insured,I was told to pay R350 for the access fee to get a new phone,I did that and sent them the proof of payment,then I was told I will be getting a samsung S5 as they don't have the Sony xperia Z1 compact,and I was told to pay an extra R100,when I was about to deposit it I called again to make sure and I was told different stories that no I can't get that S5 I will have to pay more than R100 for it,I was put on hold by several call centre agents others hung up on me they refused to let me speak to the manager,I was told that I could get other phones if I paid the R100 but not the S5 when I asked why was I given incorrect information all along,they would just hang up on me or tell me that they will have to confirm with their team leader they will call me back or email me the correct information but I have been getting this empty promises for days now.I have been without a phone for over a year now a phone that I pay for and the insurance that I pay for.Can you please help me you are my last hope,I'm really tired of calling Csurance every day without any progress.The call centre agents have not being helpful at all.Thank You in advance.
