Received a one ring call at 2:24 AM my time. It say "checking calls" when I looked at my phone.

This call came in on my business mobile line at 11:25pm yesterday but i did not have the phone turned.  Missed an earlier call at 8pm for the same reason but the last two digits of the phone number was 40.   My bank card was recently compromised and I wonder if there is a connection,

My bank card was also recently compromised; it was caught quickly, cancelled, and a new card was issued - in other words, they got nothing from me. I'm thinking there might be a connection.

Called at 11:30 pm, when answer,  no one there.
