Calcutta Electric Supply Corporation [CESC] — not getting refund

Address:

Hooghly, West Bengal, 712138

I cancelled a booking on 10th september, 2017 in west bengal forest department corporation lava nature resort due to the unrest in hill but till date i have not received the refund amount in my bank account. I wrote several times to the official mail id of wbfdc with the copy of cancellation receipt generated through your website but all my efforts had gone in vain. I tried to call the phone number of wbfdc but nobody is picking up the phone. I feel cheated. I spoke to accounts department of wbfdc but no result came.
My cancel id is - c/onl/09-17/276
Cancel receipt & tax invoice no. Wbfdc/eco/01137/17-18 sac no.9963
