I am a freelance photographer. worked for a brand. I got their products in my studio for photoshoot. Verbal agreement to return their products only after payment of the due amount. we shot and delivered the shoot. And raised the invoice.
After they got the photographs, they are not paying, and asking me to return the products or they will charge me the retail value of the products if I don't return it in 1 or 2 days.
Prior police complaint try to collect some documentary proof or some telephonic conversation 0llrecording that you entered into agreement though verbally and some witness was present at that time who can vouch for you. this wiiestablish your good case of recovery
your issue comes under Law of Torts. you can write letter to them for your payment. If they fail to respond issue legal notice through lawyer. Still if they fail to make your payment file damages suit against them for breach of contract.
