In addition to multiple calls and not leaving message, tried calling this number.  Get the standard recording "We're sorry, your call cannot be completed as dialed or the number has been disconnected.  Please check..."  How can this be?  How can you receive a call from a invalid number?  Will the telephone carriers let you put down a phony number to be displayed?

Everyday, more than once a day this number calls my home. Try to call it back get a recording, not a valid number. Is there anyway to stop this annoying call? The company, person, whoever making this call, do you ever take into consideration you maybe calling a cancer patient who just got to sleep and all friends and family know not to call unless it's an emergency, what gives you the right to manipulate your way into causing pain and suffering into my home, must I disconnect myself from the world to get away from you? PLEASE STOP!!!! At least be on the phone when I answer so I can explain not to call again.

they call several times a day, leave no message.  Please stop.

Called twice today (Saturday) first time at 8am (way to early for anyone to be calling unless there's an emergency) 2nd time 10:15. FIrst time the woman asked if I was Yann I said no this is Barbara - she hung up.  The second time - same woman simply said Yann and I said Yes and she hung up.  I don't understand what this is about - Yann is here and i'm happy to give him the phone. Can't seem to get past being hung up on as soon as I answer the call.  I'm going to get an air horn so that I can answer these calls properly.  I KNOW FOR A FACT THAT I DON"T WANT ANYTHING THEY ARE "OFFERING".
I think if they call before I have a chance to get the horn I'll simply answer the phone "LOSER".
