We're getting these two. On multiple lines. Looks like a telespammer. Caller ID shows as 'Grand Prize' and call is originating (apparently from Tulsa, OK - Zip code 74126)
Out of interest, I called the number back and got a pre-recorded message stating that if you do not want to receive calls, press 1 and then it hung up. But I have my doubts if this will stop the calls. The message says that the calls are "Promotional offers". Telespammers again.....
OK, an update... Its been about 24 hours since we called these spammers and asked specifically to have our phone number taken off their list. However this morning, their robo-calling continues.
