I have been receiving multiple phone calls per day from the phone # 830-255-4543 and I have not answered it since the calls are usually while I am at work or driving and I know I am not behind on any bills so I just ignored it. Today, while at work, I received 15 phone calls from this phone # within a 3 hour span. I decided to call the number back when I was on break to tell them to remove my phone #. A man answered the phone as "United States Social Security Office" and I said "Yes, I have been receiving multiple calls from this phone # and I want to know why". The guy immediately hung up on me. I called the phone # back and it was a generic recorded woman’s voice saying the caller is not available at this time.
