Teletech TV Repairs Theft

After 4 weeks of being ignored by Prince (the owner of the business) and his associate Michael. I have been advised that my tv that was collected 4 weeks ago has been damaged. Prince broke my screen, advised it was being repaired though after advising it would be returned (for the 100th time) is now no longer opening messages that are clearly being received as he is online every day. All the numbers provided all now go to voicemail. Against all hope I now am filing a police report of theft and will need to get a private investigator to have my tv returned.
