This number has called my house before, but I never answer unknown numbers, and they NEVER leave messages. I found this to be shady, so after researching, it appears that I am not the only one getting these calls. Sounds like it could be an illegal action taken by card services.
Automated female voice offering carpet cleaning service. Seems to be calling numbers in ascending order. I have two numbers 1000 apart (i.e.: xxx-xxx-5xxx & xxx-xxx-6xxx) and they were called about 90 minutes apart w/ same automated femals voice offering carpet cleaning service. Listed through to end and didn't press 1 when asked to. Hung up 10 seconds later. Not heard back since. Both numbers on Federal and state (PA) do-not-call list; sigh.
I tried calling 215.987.5487 ... received telephone company message that number is not in service, etc. ... so apparently caller is spoofing number Caller ID shows. I did report violation to "Do Not Call List."
I got a call from this number today (Thursday) at 2:48 p.m. but no message was left. The name on the caller ID is PENNSYLVANIA. Probably a business cell phone number. Well, I called the number and it says: not in service.
