I've been receiving several calls a day from this number ..so far today they've called 10 times. When I answer all I get is a loud continuous beep. When I call back it sounds like a fax machine. This is really getting annoying. I work at night & sleep during the day , which I haven't been able to do much of the last few days. I can't (& shouldn't have to) turn off my phone as my 83 year old Mother lives with me . Since I started this message they have called 2 more times. Is there any way to block or stop these calls? Please someone help.
