Keeps texting me about bank accounts and debit cards being deactivated unless I call their hotline. I haven't called their hotline since it is no doubt a front for some scheme.

I received a text from this number as well, with the line that it came from "First Savings Bank" and that  the card has been temporarily deactivated, suggesting I call 215-344-1605.  I do not have any accounts at such a bank, nor does my card match any of the numbers they put in the text.  It is probably a scam.

It's probably a scam because the account is non-existent in this household.
