Received 2 texts first within 1 minute of each other. "Please enter 9461 into LINE within the next 30 mins." next "Please enter 8928 into LINE with the next 30 mins." I didn't respond and my cell started ringing with 'Unknown' #. 2 voicemails left- Female automated voice, "thanks for installing line your verification code is 9461" repeating over and over for 30 seconds. Note is doesn't say, "thank YOU" but "thanks" very informal. Both voicemails gave the same verification code. I blocked the text # and haven't received anymore but it hasn't been 24 hrs.
