[Resolved]  Flipkart — product installation not done and return also not accepting

I've bought a dining table on Flipkart and its been delivered to me on 27th of August 2018 and it is supposed to be installed by them by 28th of August 2018. But till now its not yet done. Regarding this, I've already raised a complaint with them 31st of August. Till now they are saying that they are working on it.
I said I will return the product when you can't install the product, they are saying that return can't be done without installation happens. If I ask for do the installation, their answer is that our team is working on your complaint since a week. No progress till now. Everyday they are saying that give us 24 hours more.
