I had paid my electricity bill of July month on 30/07/2020 through online payment of amount rs 1450. That time amount of 1450 rs was deducted from my boi bank account but transactions failed and some error occurred. Now payment of July month is not showing on the official website of msedcl, not in bill history and payment history. Please refund the deducted amount
