new contract an no phone

ordered a new contract on the 28 April 2021. Courier company was notified to change the address to a new one they couldnt update so they took the phone back. called Vodacom and guess what they took my order and gave it to another customer. Did another order and they decided to cancel it as it shows duplicate. New order again 6th May 2021 new sales person requested to send documents to them which was done . no reply from they they say they waiting for authorise it from back office. keep calling them no answer spoke to different team leaders they cant assist guess what they dont have the phone so they cant answer. all i want is they give me a replacement as they cant deliver i even have a tax invoice from them. really disgusted with there service . the call centre guys dont even know there managers name how sad .....
