First call was a robo call. I called the number and a female named Sandra answered the phone. She asked for my number I didn't give it to her nor my name. I asked the nature of the business . She stayed some kind of processing service. She asked for my number again I didn't give it to her. I asked her to explain to me the nature of this business and she hung up on me. I called back several times asking the same thing and she kept hanging up. This is some kind of scam.
