Tamil Nadu Electricity Board [TNEB] — PMC billing was wrongly updated as very high billing claim

I am Karthikeyan from Anna Nagar, Chennai. I took a commercial site for Coaching Business in Anna Nagar East. Due to the government order, we have stopped the admission progress and shut down the coaching academy in April itself. But for the current EB billing its shown as Rs.32, 265. But for the last billing we paid is Rs.3, 322. As per the PMC calculation mentioned in the "CPRO Press Release dated 05.05.2020", it says last billing amount to be paid as PMC.
But the TNEB raised the billing with Rs.32, 264. During the Pandemic Situation, its unaffordable one for me. Before the billing date, I am requesting to correct it.
Also I raised the complaint in the TNEB online portal and the complaint completed without any actions.
