you're not the only one having that kind of problem. about 3 months ago i only paid 10QR for 2 months, that's just the meter rent and then on the 3rd month i got my kahramaa bill which was around 300QR, which was not my usual payment for a monthly bill.

the kahramaa staff assigned to do the reading are either lazy, useless, just plain dumb or just think of some numbers just to show that they are doing their job!
