I am having the same issue, with the exact same number. They are calling my cellphone, multiple times, all throughout the day, & evening. Sometimes they have even called as late at 11:00 at night!! No matter what I do, if I answer, the line goes dead. Whenever I try to call back, it doesn't even ring. It will just sit in silence, until the line goes dead, and it hangs up on me. These companies should not be allowed to do this stuff!!! So irritating!!!
