Indraprastha Gas Limited [IGL] — Incorrect GST charged

BP Number [protected] was re-connected on[protected] and the bill was generated for the same. This bill contains incorrect GST of 98.84+98.84 for which there is no base amount. Called up helpdesk several times and emailed them several times however they are saying that this is charged as no consumption.

I re-iterated that BP was "Temporarily Disconnected" for which I have already been charged separately.

Additional Tax as mentioned does not arise at all, and if so what is the base amount for this.
