Bellagio poor customer service

I booked in my Chopard pendent for repairs in December 2014. Granted it was over the festive season and the pendent would only be sent to Switzerland in early Jan 2015. After several attempts to find out where my Chopard was, Sebastian continues to spin a different story. It's now five months later and there is still no sign of my pendent. The owners of the business also have no interest in responding to emails. I urge anyone planning on handing in any repairs to Bellagio not to do so, since it appears that mine has gone missing. The Ballagio staff doge any opportunity to tell me where the pendent is. The only thing I can do now is contact Chopard Switzerland to try and track my pendent, and lodge a formal complaint against them. I doubt this pendent ever left our South African s****s. It is also the most irritating thing dealing such *********** people.
