Starting to get calls from this number and I suspect they are the same assh*les who are also using a Jacksonville number and also a 941 area code number. I am registered with the Do Not Call list and I will log every junk call on the Do Not Call online complaint form. If your number is registered with the Do Not Call list, go to the Do Not Call website and fill out the online complaint form to document these junk calls. We all need to document these calls so they get closed down.
I get calls like this all the time. I used to work for an outbound telemarketing firm. Your best bet is to answer calls that come to your phone instead of letting it go to voicemail. If you let it go to voicemail, and the call was made in the AM the caller will mark their system for either AC (Afternoon Call) or EC (Evening Call)...this is why they keep calling back as they are trying to reach you.
If you answer the call and just make up a business, preferably a law firm (say "thank you for calling Smith & Jones, Attorney at Law, how may I direct your call" they will not say anything, hang up, and not call you back as they will code the call as a business or WN (wrong number).
This deletes the number from their system until you sign up for another credit card, use your debit card or credit card, fill out a survey, etc... and they get your number again. Just my 2 cents
Received call from this number. When I answered the caller was silent for a few seconds before disconnecting. I have heard of computer robocalls that test to see if anyone answers. They've probably sold my number already.
