Samsung has "lost our tv" Reference JC144191

we sent our TV in for repairs , during the month of Sept 2017-to the Roodepoort Samsung Customer care Repair Centre (14th Ave), we received a quote and paid on 20 Oct and on following up with, Samsung -we found that Samsung has closed the repair shop. we have tried to locate our TV and are told that we need to produce the original slip of paper we received when handing the TV in. We don't have the slip of paper however we have the quote JC144191 and proof of payment for the repair. Plus we have emailed these documents to Samsung over 4 times. They are unable to locate our TV and keep asking us to email them the same documents over and over. Please can some one urgently assist us in getting our TV back!
