This is a scam trying to get your credit card number.
This number calls my phone daily! I don't know how they got my number but I am sick of their calls. I sent them a text back to the number stating they do not have authorization to phone me and to remove my number from their list. The calls are still coming in so I decided to come to the internet and make a complaint.
