Just called my mobile # (yes, on do-not-call list). I get MANY calls from 210 area code with various exchanges. ALL are spam. These [***], like all the others, do not leave messages. I have a growing list of 210 area codes.
Called me this morning and I simply declined the call. No message was left and I have received calls like this from other numbers in the San Antonio area. No doubt they are eager little beavers.
