Eureka Forbes — Installation issue and no proper response from customer care

I purchased water purifier from Flipkart and it got delivered on 30/09/2022, installation should be completed by Eureka Forbes and request id was created by Eureka Forbes on 30/09/2022, however till today installation is still not completed and it's almost 6days and I have contacted them 9 times and there is no proper response or no one from Eureka Forbes contacted me about the issue. Every time customer care girl says work id is already created and they don't know why it is delayed and they say they will escalate the issue and disconnect the call.
