Livpure — Not satisfied with the customer service

2 weeks back I requested for service and person came for service and changed all the filters. He said external filter has to be fixed since it’s bore water so sand got deposited. And external filter cost will be around 700rs he said. I asked to bring and fix external filter inorder to avaoid this sand issue. He said he will come and fix in 2 days but its been more than 2 weeks still he didn’t fix it. Service ticket is closed. That person is not picking my call also. This is not the way customer service should be.
