I have been getting this call every day for a week. By law if you call them and leave the message not to call you back they must comply. Also record the call. If they don't that recording and the cell phone bill showing time and date of your call will come in very handy.
Have gotten 2 calls per day for last 2 days. Just a minute ago. The number didn't look familiar so I Didnt answer but always look up # I don't know. Have had my # for years, & has been listed on do not call list. You can block # on Verizon mobile. I'm doing that first.
