Alpha Movers stole my belongings

I hired Alpha Movers to move my home contents on 31 October 2020. The move went well but only to find days later that the people who were moving my furniture stole my 1TB external hard drive , 2 smart watches and they even stole my daughter's Trinkies cakes from the arm rest compartment on my couch. I contacted the Sales Manager Mr Adrian Patrick and his investigation did not come with any outcomes. I am really disappointed at this company.
