Vodacom cannot provide a last usage date for an insurance claim???

I have been in an attempted hijacking on the 14 November 2017 and reported my phone to Vodacom, had this blacklisted went to the police station all of this. I placed a claim with Mi Way on the 15 November just to be told yesterday that they can wait for Vodacom for up to 30 days to provide a last usage date, but when I called today they could give this over the phone to me? How come this cannot be given to the insurance company? I spoke to Tseko and then Simphiwe and all they can say is that the system does not allow them to get this information sent to the client or insurance nor a screen dump we have to wait for the billing to close how beautiful. So how long do you want me to wait for a replacement or claim to be done?????
