Stargas very poor service

Stargas is the only agent for Kwikot gas geyser After waiting for 2 days to come and have a look.They came and fix a flow meter but not the problem Then they gave me a lone unit after another 2 days Then after 11 days they send me a new price The price to fix a geyser is over R6000 in total. This is ridiculous If it is Kwikot or Stargas the bottom line me as a customer are getting nailed
