Caller ID: DUCT PROS. This same phone number also uses the Caller ID: HVAC CLEANING and CLEANING SERVIC. And the first 6 numbers are always 240-318-xxxx. The last 4 numbers tend to vary but it's always a duct cleaning telemarketer.
I get a call from this # at least once a week; sometimes it says cleaning service, sometimes Duct Pros, sometimes no ID….they get my answering machine but never leave a message; we do not answer the phone at all but they are still a pain in the [***]; not sure what they hope to accomplish?
