Sir,
I am quite surprised and quite shocked to receive the electricity bill amounting Rs. 1747/- against electricity consumption for the last 3months where we didnot use this much electricity.People from electric dept. told us that they will help but I didnot get any type of resolution from their side.I also raised 3 dockets in wbsedcl online portal .But I didnot receive any type of solution .Kindly help me Sir.
