Electricity Bill — I am complaining about april bill

Address:

Mohali, Punjab, 160055

I want to raise issue that i am facing regarding electricity bill made for april. As we are two girl's living in rental house and we changed house from april. And when i got bill, bill generated wrongly i. E. 34270/- and some arrears curr. Fin. Yr. Amount added i. E. 26480/-, this bill includes units dated from 12 feb to 12 april. When i asked to landlord to check it your end with electricity board then i came to know feb bill is not generated in pspcl side. And they re-generated another bill after correction with amt. 3430/- as i always received emails regarding bill generated of 2 months. But didn't received feb bill.
And new bill includes units dated from 13 dec to 12 april, now arrears prev. Fin. Yr. Amount added i. E. 1707/-
I asked to landlord it's still not correct as always arrears any is 0 i want to know 1707/- is for what. He said go to electricity office at your end. I do but in electricity office, employee didn't give me satisfied answer and told pay 3271/- instead 3430/- as feb bill not reached to you now estimated bill generated. As we both are working didn't get time to figure out why they put arrears prev. Fin. Yr. Amt. So clear this as with living of 2 person's moreover not at home 24 hrs. Always bill is not more than 2000 generated
If feb bill is 860/- then let us know april bill (March, april) bill. If i subtract 860 from 3470 then, 2610/- is the bill of april which is not possible.
I don't understand this mistake occurred by pspcl or by landlord added any previous units in the bill.
Please resolve it asap. I am not going to pay this amt 3470/- as i know worth of money and my rights.
