Chennai Packers & Movers — broken the luminous inverter and stolen some new shirts, including a new costly shirt taken for wedding.

I recommended "chennai packers and movers", kolathur, chennai, to my sister from ramavaram to arasamarathadi, near kk nagar area, chennai. They charged 5000inr. And cash paid. But, no cash receipt issued, even though it is demanded by my sister. The workers broken the luminous inverter and kept & went silently. Also, some office wear shirts and a costly wedding shirt of my sister's son were found missing. Tried to lodge a complaint, no one is picking up the phone. What shall i do? Please suggest.
