Not fulfilling the work for which they has to be paid

I booked a modular kitchen from UltraFresh modular kitchen solutions on 1st week of June and paid 10% payment. According to the policy we submit whole amount of modular kitchen till 15 August. They send the kitchen part and build our half of the kitchen, but after that company didn’t pick our call n not completed our kitchen till date. We book through an agent mr. Naveen Saini, he also not responded and tell us wrong information and mentally Harras us.
