They showed up at my door at 7:15pm with no notice or invitation. Claiming they need to confirm something on my Hydro bill, 2nd or 3rd page. I asked why that couldn't be checked on the back end from an office and he seemed stunned. I asked for a card and he handed me a blank card with no rep name or rep number. Cleary a scam.
