Who called from 4752230248

This number just called my cell phone.  I did not answer. They did not leave a message.  It's bad enough these calls come on my home phone, but really annoys me when they come on my cell phone.

Just received call on my phone.  No message left.

called 3 times within 3 minutes with no message

Called my mom's phone and asked if she would "accept the call". Mom hung up on her.
Said the person sounded very professional and legit. Caller said she was calling from Derby, CT, where we have family.

Received a call but left no message. Caller ID says Derby, CT but I am from CT and there is no 475 area code
