Ro Care India — AMC technician refusing to come

I was told by Brijesh to get an AMC for 12 months for 4000 Rs about 2 months ago. However twice from last three days I have called RO care india as my RO needs urgent repair and I don’t have water at my home. But the entire technician staff at Goa are celebrating Ganpati at Mumbai and they are not available at Goa. I want my refund for AMC
