This number 512-487-4896 calls EVERY day, never leaves a message, and when I try to dial it back it is always a busy signal. I've blocked the number now, but my phone still rings once every time they call, every day. I wish I knew who this was so that I could complain directly to them.
I have received 2 calls this morning within 30min of each other. I used my work phone to call them back and received an out of service message from Verizon. Definitely a cloned number.
