GSPC GAS COMPANY LIMITED
Eventhough we submited cheque before due date they are Forcing me to pay bill with Late charges

I have GSPC gas line at home, I receive GAS bill of 384/- RS and i drop my BOB Cheque for same amount, my due date of Bill is 9/25 (mm/dd/yyyy), I have writtern same date on cheque,

MY customer ID is: "GNR110614021528"

Now after month when i checked my Bank statement, i found that my bill amount is not deducted from Bank, so i called to nearest branch and talked with him, he called me for face to face meeting, when i went there that executive agree that they recrive my bill cheque before due date, but taht is advance date cheque so their system is not allowing them to redeem that cheque and on taht day they forgot to redeem my cheque so now that due date is gon,

now i have to pay Bill with late charges, still i am not getting whats my fault, if their system have some provision for advance date cheque they they should inform me atleast once in advance,

i am very upsets with their employee's attitude and i have given compain to local branch manager but didnt recrive any updates.
