Dissatisfied and disappointed client

I am very disappointed with the service received from RAM. On Friday I was advised my Shahnaaz that I will receive my device on Friday 08.12.2017 (which was her response on my complaint) when i called my service provider to do a follow up with RAM she advised them that the vehicle that had the parcel was hijacked (which i only found out on 08.12.2017 when i did a follow up) when i asked her why did she inform me that the device would be delivered on 08.12.2017 the only thing she could say was '"sorry that was our mistake and I do apologise" (she actually **** to me) ... i received an email from her on 08.12.2017 and she advised that I need to forward the new waybill number and I responded on her email on 11.12.2017 informing her that i have not yet received the new waybill number and she advised that she will contact Vodacom and get the new waybill and that they will try for delivery 11.12.2017 latest would be 12.12.2017. and i asked her why did say that they will deliver on 11.12.2017 and i suggested to her not to make 'promises' to the clients that she is unsure of. I called in on the 12.12.2017 I still have not received a new waybill number and when i wanted to speak to shahnaaz she was unavailable and no one is able to assist me.

Can I Please get a update on this. URGENTLY!!!!!!!!!!!!!!!!!!! i am getting frustrated and annoyed wit this matter now.
