Livpure — No installation of water purifier and no refund

My rentel water purifier is still not installed after subscribing a week ago .
It's on monthly basis, my package. I already lost one week of one month . Am I gonna get the money back for one week? I had to buy packaged water for the last one week that costed me over 300 /-. Who is responsible for this?
I was told that within 1/2 days it will be delivered and installed .no news of that yet .I want my money back in full amount which is 1748/-
