Samsung Warranty and Horrible Service

I've booked our (Business) 27inch Samsung Monitor (Still under Warranty) on the 3rd of April 2018 at Unitronics (Samsung Service Centre Century City). The Technician said it will be a couple of days to fix it but they will contact me as they are in the process of moving to a new premises. I've received no communication by the 23rd of April 2018 and decided to go to the service centre to see whats the status as they don't answer phones. A sticker the front door of the building said that Unitronics is closed and we should contact Samsung Call Centre. I contacted the call centre immediately and was told that the monitor is fixed but they can't see where it is, they will call me back. I phoned the call centre again on the 25th of April 2018 and still no status on where my monitor is and yet again they will phone me back. I've contacted the call centre today again (2nd of May 2018) and still no status but they will call me back (WHATEVER).

I think this is horrible service and will never buy any Samsung Product again and will advise others to do the same.
