cng is a blessing for "safaid posh" people
welcome to the club
unfortunately the emulator and advancers are being made locally probably in gujranwala
and i have been a victim of this crap just like u, in my idsi city
the catch ............these installers have printed sign boards in shops "no guarantee for electrical parts"
but since i went through a reference, they were kind enough to change it 2 times for free.
third time when it messed up after 2 weeks they asked for money. but again they agreed to split the hit. i just paid 1200 rupees, and so far its working fine
b.t.w i am against hot water connections. can discuss later.
CNG complex is reknowned for there quality and neat fittings. i am sorry they didnt entertain u when u returned
