Hi,
My acount I'd is[protected] and address is e 418 shipra krishna vista apprtments indrapuram.
Kindly address following big time issues
1)I need understand what should be the billing cycle, 1 month or 2 months or 15 days or it is at the wish of that private guy hired by the department because I have revived bills for all duration latest for 21/04/16 to 09/05/166.
2)I have made a payment on 5th may this bill is generated on 10th may amt rs 6164 but still my last paynenyt is not reflecting and I have been charged late fee ..why.although when checked online it's rs 3148 why there is so much issue.
3)my bill amt remains same always whether it's for 45 days or 14 days ...this time the bill is for 483 unit in 14 days while last time it was 463 for 45 days ...how is it possible...the consumption pattern cannot change so much till there is some external factor
Kindly address the following else I would be forced to go to consumer court but in any sense I cannot tolerate this nuisance by the department...I am available on phone as well [protected]
