Delonghi machine lost

Bought a Delonghi espresso machine in September 2015. Milk frother broke and I took it in to have it repaired because it is still under warranty.They called me last week to say i must bring the accesories of the machine to test if its now working. When i got there yesterday no one at the shop knew where my machine is or if it was still at the place where it was suppost to be repaired. I also found out that they did not send the machine to the Delonghi factory to have it fixed but to another mechanic(apparently an accredited service centre-not good enough because it is still new) .Everyone at the store was so useless and was standing around and didnt know what to do, the store manager was on leave and now no one there knows what to do. I called a rep from Delonghi to report the situation because I realised at Dion no one is going to help me. And another day later and still no one called me to say where my machine is. This is pathetic service from Dion Wired Rustenburg. Also called the warranty dept and the lady put me through to another guy at the customer service department and also got a bad attitude from him and also couldnt even give me a reference number for my complain.
