Rentickle.com - Package not delivered

I have ordered a fridge, washing machine and an RO from Rentickle. I have done the payment and submitted all the documents but they rejected my order by saying your credit score is not good but when I checked my cibil it was more than ***. I shared them my screenshot and they replied sir please pay an advance of * more months. As I was in need I have done that payment too. They assured me that my things will be delivered in * days. But no one responded properly after payment. The supervisor doesn't pick up my call and says it will take time. Finally, they delivered two items fridge and RO but no washing machine. They have done ECS mandate, the contract was signed but when I asked about my washing machine they said it is out of stock. No one has come till date to install the RO machine. When I call they say RO will get installed today but no one comes. I ask for washing machine they say you can cancel the order. What type of service they are providing. I am mentally harassed and fed up with this company and its service.
