I've seen this # call the house before. A woman claimed she was from Macy's, that we had a late bill, and asked if we could send money over the phone. This was probably correct, but as a rule, always say "no" if someone says that to you. Ask them to send you a bill instead and do not give out any personal info. If it was someone from Macy's, they would have all your info anyway. It's much safer to pay a bill through the mail than over the phone, when questioning the validity of the person who called you. The caller ID read MCCS, and Macy's does have a service with that acronym, "Macy's Credit and Customer Service" or MCCS.
