Just had a call from this number.  When the call came in, the display showed "Luxury Med Corp," Yet, when I answered the call, they offered to lower my credit card rates and would not give me the company name.   As I retired librarian, I decided to check further.    I was unable to locate Luxury Med Corp.  either in Massachusetts or anywhere else for that matter, When I tried calling back, was told it was not a working number.  Fairly obvious it is  not legit.
