If you receive a text message from "Brattleboro Savings and Loan Association" saying "Alert for (your phone number). Call 347-218-4082." YOU PROBABLY SHOULD NOT CALL BACK. I think it's a scam. The phone # is listed as an NYC number, and the recording told me that my ATM card is frozen. I do not have an ATM card with BSnL. It asked me to type in my account number.
If you need to contact BSnL, it's probably best to call the number they list in the phone book or online, not the number in this text.
