Short answer
Energy back-billing complaint enquiries should identify the supplier, account, bill period, meter readings, previous statements, direct debit history, complaint date, vulnerability records, deadlock letter or eight-week timing. Legal4U cannot decide whether a bill is accurate or whether money is recoverable.
