Tamil Nadu Electricity Board [TNEB] — Shifting of EB pole

Sir/Mam, the EB pole is found laid inside our patta land near Fomra college, Thaiyur. On asking the EB department, they are demanding for expensive charges around 15 thousand rupees as fee and other personal charges. As you'd know EB poles are not supposed to be laid especially inside patta land, in such case, how are we responsible for paying the charges for something the dept did without caution.
