My caller ID also said Sandiegobldbnk, but when I called back, It was something to do with AT&T.  Told them I didn't want to switch and to not call me again, they haven't, but before that they called a lot.

Caller ID Says: San Diego Blood Bank but it is AT&T were trying to get me to switch back, I cancelled my AT&T more than a year ago.  Called 5 times before I finally was home when they called.

619-768-5728 belongs to AT & T and they are trying to sell equipment!!!!!!  They are misrepresenting themselves by identifying themselves as the San Diego Blood Bank!

No message. My caller ID said it is a San Diego BLD BNK.
