Punjab State Power Corporation [PSPCL] — wrong bill of electricity

Address: Mohali, Punjab, 140603

My name is Abhijeet Resident of zirakpur. I have consumed only 50 units of electricity as showed in Electricity bill and by meter but pspcl has put a cost of 1220 Rs which is wrong and discriminatory. They keep harassing public. The bill has been attached for reference.
This has happened 2nd time with me. Last time too they put sundry charges in heavy amount. But this time They have put an exorbitant amount of 1220 rs for consuming only 50 units of electricity, as I was out of city hence my units consumed was 50 .
