Same I experienced for Rayyan water . I complained too much but no permanent solution . Then I bought 6 bottles ( 20 liters each ) . I asked them to come weekly once - they fixed one day in a week . I told them that I will keep empty bottles out side my home entrance & will keep money / coupon below empty bottles . Now system is working - I am keeping my bottle out side - keeping money below bottle . They are coming any time in a days & delivering full bottle . This system is good - I didnt saw delivery man's face for last 3 months but there is delivery & its goinng on . I have more bottles so I am not facing problem what u r facing .
