Sunflame Enterprises — sunflame burner - installation tech not good

Address:

400042

I bought sunflame burber from vijay sales ghatkopar. Delivered on feb 8th 2019 friday. Technician himanshu came on 9th to connect - service charge rs.350 + rs.250 for hosepipe total rs.600 which i paid cash. He put a 15 inch hose pipe with no clamps on both ends despite requesting 1.5 meters tube. He saud will come back with it as he didn’t have that. I cannot move the burner away from the gas valve or use it. After repeated calls over 15 times to company customers care and tech and complaining about the problems no one has showed up till today feb 12 2019!
Same reply - technicians are on leave or no one is in your area! First of all cannot reach customer care easily. So frustrating can someone look into this
