I receive a call from this number CONSTANTLY.  The Caller ID says "ECHOSYSTEMS".  There is a recorded message about how to "lower your interest rate by pressing 9 now".  I press 9 and get a random person each time.  They say they are with Cardmember Service and want information about our accounts to help lower our interest rate.  It is always someone with an accent.  I ask to be removed from the list.  They tell me "there is no list" and that I cannot be removed because my credit card company told them to call.  I told them I would call my credit card company directly and they get defensive and cannot tell me which company recommended them to call.  They give a generic answer of "we service VISA, MasterCard, etc.".  Bunch of bullsh*t if you ask me.  I need to figure out how to stop them.

BEWARE of these slimy callers!!  Echosystems is just another one of the phoney names, and this is just one of the phoney numbers, used by these credit card scammers!

So far they have called continually for the last half hour, so far 16 times, make that 17 times now and still calling.
I am not answering and they are not stopping the dialing, what jerks!
I am on the No Call List but it never matters it seems with so many telemarketers.
18th call now, turned off my ringer...

Offered "Lower Rates" on the supposed credit card account I have with them. (I do? How fantastic! Always wanted this one credit card with lower APR.....)

"Dial 9 to speak personally with "John"."

The call type was definitely a scammer. NOT Unknown, NOT Telemarketer, NOT any of the choices given to me in the Call Type dropdown menu below.  
Plain and simple,   A SCAMMER,    
and the name being used is John,      
and the phone number being used is registered in Midway City/Westminster, CA.        
On  Newland St.            
Behind the 14588(aprox.) street address.

(If I didn't live about 1,200 miles away, I'd go there myself and complete what the responsible  authorities can't seem to accomplish.)

I'm watching my language here.

Recorded call offering lower interest rates.  They ignore the Do Not Call List.  Recording offers no option to remove.
