My parcel was hijacked now I’m struggling to get replacement they are.

I’ve purchased the iphone to them early December and the courier company that they are using which is SkyNet World Wide has been ****** on the 9th of December while they were attempting delivery. Both these companies never communicate with me about the ******* until I went to the Wear-house of SkyNet last week Wednesday they told me they have been ****** my parcel they report to I store about the ******* but I store never sent me an email or call me until I called them My self. They said they will send me a replacement but even today I haven’t received my replacement yet and they are not responding to my emails.
