The Courier Guys loses my package and then forwards responsibly to a company with horrific customer service

My parcel was lost for some reason. The initial communication I received was that I would receive a replacement package however this was not the case. They said email saying is receive a new tracking number but this never happened and that was 4 weeks ago. Before writing this review I’ve send many emails to try solve the problem but I’m extremely tired of this horrific customer service.. I was then forwarded to deal with another company called Uafrica.com. This company needs to implement better communication processes as it took a week for a reply which did not even relate to the problem I faced. The courier guy simply ignores the fact that they misplaced a package and shift the responsibility to another company that does not strive to provide any reliable customer service.
