Who called from 2483081092

Wondering who this is from - called back to see ( know you're not supposed to do that) but got recording "The number you've dialed is not allocated" - which I assume means it's a scammer calling

I was busy and accidentally picked up phone and recording This is Rachel f on Cardholder Services. I went Click now reporting to FTC

I just received a call from (248) 904-1254. I didn't answer and they didn't leave a message.

Same happened to me today, 10-14-15.  I got the same message, "The number you've dialed is ot allocated"  Aparently being on the DO NOT CALL list is completely meaningless.

Received call, did not answer, no message was left.
