Punjab State Power Corporation [PSPCL] — extra charges in bill

Address:	Pathankot, Punjab, 145025

My account no is g56bf620876p & for this bill cycle my bill comes 8130 which is very high, when i saw the bill they charged the bill from 24 march to 26sep, while i had paid the bill till 25may also bill was come late,
When bill cycle is two month then why pspcl send bill after six month.
Also in long bill cycle we have to pay high charges, high taxes.
Why we have to pay high charge while we dont have any fault.
Plz look into this matter & try to resolve the matter as soon as possible.
Because its too high bill & we can not pay this.
