619-819-7075

Got a call from this number, the Caller ID lists it as "AT&T SVC CTR".  Call left no message on the answering machine.

Also getting calls from this number with caller ID listing AT&T SVC CTR. They do not leave a message. I do not have any AT&T services and am on the do not call list so they do not have the right to call me.

Have been getting calls, no messages left.  The one time I answered there was no one on the line.  If you call this number it gives 3 options, speak to a rep, have a rep call or be put on do-not-call list.  I picked speak to a rep, got "please wait for a representative" and then silence.  A long silence.

Got a call at 12:33pm, then at 8:40pm from this number, the Caller ID lists it as "AT&T SVC CTR".  Call left no message on the answering machine. Am on the DoNotCall List.
I thought you can't call that late???

They've been calling for about a week now.  No caller ID--just San Diego, CA.  So, today, I finally applied my favorite strategy:

Answer the call, but do not make any sound of any kind.  Eventually, the caller will start saying "hello, hello?".  This might take up to a minute until they start talking.

Then either hang up on them, or use a popular two word greeting.

Since they've been calling for a full week, I decided to use the greeting.
