Telangana Southern Power Distribution Company [TSSPDCL] — wrong billing and refund of extra amount paid towards electricity bill

Address:

Bowenpally, Hyderabad

From dec 2019 to till date, electricity bill against my unique service number[protected] is being generated wrongly. My usn comes under "domestic category" but bills are being generated under "common service category". I have complained vide complaint number cc[protected] and complaint has been closed saying it is rectified. But after that also, june month bill was generated wrongly.
As per my knowledge about an amount of rs.1717/- has been paid extra by me towards electricity bills from dec 19 to till date.
Hence i request the concerned to rectify the issue and refund the extra amount paid by me.
Thank you
