I received this call very early in the morning at 5:40 a.m.  I did not answer.  They did not leave a message.  Immediately after that I receive another call from 416-777-7775, which I have looked up and apparently that number is from a "scam company".  I want to know if anybody has received similar calls.  It all started when the person wanted to buy real estate, which I sell. I don't know if these calls are related.  How do I stop them from calling my cell phone.  I have received a lot of calls from the 416-777-7775 number.
