Hisense bad service

I sent my TV for repairs in December and because it’s still under warranty Hisense came and collected it. 2 weeks into the new year I received a message that my TV was repaired. Today is the 15th of February I still don’t have it with me. I call every third day and always get told the same story. My TV is repaired and is with the technicians who have to bring it back to me. My issue is that I asked for the technicians number and address so I could go collect it myself I was to that info is private. Now I wonder even when I do eventually get it back how can I be sure that it’s still in one peace and hasn’t been stripped for parts. I don’t know what to do anymore.
