Price lock team gave me a decoder that belongs to another customer. Damn thing doesn't work but they can't pick up who it belongs to!!

Since 01 December I've benn locked in a back and forth and a horrible service with Multichoice. After complaining and wasting time and money contacting them about my price lock deal, they ended up delivering 2 decoders many many days out of ETD and no one bothered to call. Onky to find that the one explora is assigned to a different customer and it seems no one at the call Centre besides the very useless price lock team can. It's been two days and they still haven't been able to get it right. I am supposed to pay an installer and Multichoice for a decoder that doesn't work, after such a horrible experience would think service would get better but it gets worse. The price lock team must be replaced with automated processes, they don't deserve their jobs, they super useless and very frustrating!!!! Worse of all, you can't get through to them, you are promised a call back that never happens. Upgrading was the worst mistake I could ever made. I want someone to collect this piece of ******* from my house, I'm not going to keep a device that doesn't work. I am not going to pay the installer for a secomd installation but I can't watch TV. It's useless!!!!
