How to escalate a BEST complaint

Forward the complaint number to your group so nobody has to search for it mid-outage.

No toll-free/1912 number is published by BEST; complaints go to zonal landlines or ward fuse-control centres (each with its own WhatsApp number). The WhatsApp number above is the general customer-care WhatsApp shown on the complaints page. Tata Power also holds a parallel licence in the BEST area.

Complaint not fixed? How to escalate

Every distribution licensee in India must run a Consumer Grievance Redressal Forum, and every state has an Electricity Ombudsman above it. Work up the ladder; keep your complaint number from step one.
