Number overview
0120-829-571 is a Free Dial number (the 0120 prefix). Numerous reports describe calls from this number using names like "Electricity Rate Survey Center" to disguise themselves as electricity-rate surveys.
Reported behavior
- The caller identifies as "Electricity Rate Survey Center" or a similar name
- An automated voice runs through a survey about electricity rates
- Once you answer, follow-up sales calls about solar panels, storage batteries, or switching to a new electricity retailer are made by a live operator
- No public agency by the name "Electricity Rate Survey Center" has been confirmed
The Consumer Affairs Agency warns about phone solicitations that impersonate public bodies. A genuine public agency does not normally call individuals to survey their electricity charges.
How to handle this call
Don't engage with the automated prompts
We recommend hanging up rather than answering the automated survey. If you answer, you may be added to a list of "interested consumers" and receive further sales calls later.
Be alert to calls posing as public bodies
Even when a caller uses names like "XX Survey Center" or "XX Association," confirm whether the body is a real public agency. If anything looks suspicious, hang up and verify on the official website.
