Flipkart — Water purifier installation

Website:

Flipkart

Hi Team,
I ordered a water purifier from Flipkart and it is delivered on 10th of April but the installation team is not showing up.
I raised the issue to Flipkart on 6th of May regarding this and they informed they will provide the service by 10th of May, but as of 29th of May they didn't provide the service and everytime when I called them they will be saying it will be sorted with in 24 to 48 hours and they are just extending the deadline.
I lost my patience to them and last few days I was asking for refund and take back the product but they are not willing to do it
Just one team is saying on other team and just passing the time .
Is there anyway I will get the resolution to this
